Does ESTRUS Mean?"},"content":{"rendered":"\n<p class=\"wp-block-paragraph\">\u201cEstrus\u201d is the biological term for the period when a female mammal is sexually receptive.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In everyday language:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">in heat.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">So yes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo really named her album after that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But the title is doing considerably more work than simply announcing that this is a horny pop record.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo has explained that she wanted a word capturing something:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">animalistic<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">primal<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">vulnerable<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">restless<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and emotionally unstable.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">She eventually found \u201cestrus\u201d while looking through a book about cats in her Los Angeles studio.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The definition immediately described the emotional state she had been trying to name.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does estrus mean scientifically?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Estrus refers to a stage in the reproductive cycle of many female mammals.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is the point at which the animal is physiologically ready to mate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That makes the word feel very physical.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hormones.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Instinct.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Body before logic.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo liked exactly that quality.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Her album repeatedly explores moments when what your body wants and what your mind wants are not remotely the same thing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Anyone who has made a catastrophically poor romantic decision while being completely aware it was a catastrophically poor romantic decision may understand.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why did Tove Lo choose the word?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">She was looking for it without knowing it existed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">During periods when lyrics are not coming easily, Tove Lo sometimes browses books for words or ideas.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While reading Feline, she encountered a definition explaining that a cat \u201cin heat\u201d is in estrus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That clicked immediately.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">She later described the state as simultaneously:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">feral<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">sensitive<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">anxious<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">vulnerable<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and driven by primal impulse.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That mixture reflected what she had been feeling while creating the album.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Is ESTRUS just about sex?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sex is obviously part of Tove Lo\u2019s writing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It generally has been.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">But ESTRUS is interested in the emotional contradictions around desire rather than simply desire itself.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wanting someone can make you feel:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">powerful<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ridiculous<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">confident<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">jealous<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">alive<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">insecure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Sometimes within the same twenty minutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The title captures that instability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pitchfork noted that even the word\u2019s linguistic roots connect desire with ideas of frenzy and madness, making it an unusually appropriate title for an album moving between pleasure and anxiety.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why does Tove Lo call the album \u201cfeelings with no solutions\u201d?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because the record is not offering relationship advice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That appears to be deliberate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A lot of pop writing eventually arrives at a lesson.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I was hurt.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">I learned.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Now I know better.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ESTRUS is less organised.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo\u2019s own description is essentially:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">many feelings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No reliable advice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That gives the album permission to contain contradictory emotions without resolving them.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Which is probably closer to real relationships anyway.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why did the album take four years?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Writer\u2019s block.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo has said she returned to the studio with longtime collaborator Ludvig S\u00f6derberg at the end of 2024 and initially struggled to produce anything that felt right.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That experience frightened her because writing had rarely been that difficult before.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After years of the:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">album<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">tour<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">album<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">tour<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">cycle, she had deliberately given herself more space.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Apparently the creativity did not immediately thank her.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Eventually the uncertainty itself became material.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where was ESTRUS recorded?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Across:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Los Angeles<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Stockholm<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">and a small Swedish fishing village where Tove Lo spent childhood summers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That village has become particularly important to her creative process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">She associates it with major memories:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">first relationships<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">family experiences<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">heartbreak<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">depression<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">loss<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">growing up.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Returning physically to the place seems to unlock emotional material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That makes the album title even more interesting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The record may sound physical and immediate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A lot of its emotions come from old memories.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What genre is ESTRUS?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Electropop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dance-pop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Club pop.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are also clear Scandinavian electronic-pop influences.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo has cited artists including:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Robyn<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Knife<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lykke Li.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That lineage makes sense.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Swedish pop is famous for immaculate songwriting.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These artists often use that precision to describe people behaving extremely imprecisely.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does \u201cI\u2019m Your Girl Right?\u201d mean?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Even the punctuation tells you something is wrong.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The phrase sounds confident.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">right?<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Suddenly confidence becomes insecurity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That tension fits ESTRUS perfectly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The production can feel euphoric while the narrator is:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">jealous<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">uncertain<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">obsessive<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">or questioning where a relationship stands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Again:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">body on dancefloor.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Brain conducting an internal investigation.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Who appears on the album?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Stromae is the album\u2019s sole featured collaborator, appearing on \u201cdes fleurs\u201d.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The limited guest list keeps the emotional centre firmly around Tove Lo\u2019s own writing rather than turning the record into a sequence of pop collaborations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Songs to hear if you like ESTRUS<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Robyn \u2013 Honey<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Knife \u2013 Heartbeats<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lykke Li \u2013 I Follow Rivers<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Charli xcx \u2013 party 4 u<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Romy \u2013 Enjoy Your Life<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">COBRAH \u2013 Good Puss<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">SG Lewis &amp; Tove Lo \u2013 Heat<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo \u2013 Habits (Stay High)<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo \u2013 No One Dies From Love<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why is ESTRUS such a good Tove Lo title?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because it sounds:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">clinical<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">sexual<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">slightly disgusting<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">strangely elegant.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That combination is very on-brand.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo has always been interested in what happens when polished pop meets behaviour people normally avoid describing politely.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">ESTRUS turns that entire philosophy into one word.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does ESTRUS really mean?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Your body wants one thing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Your brain wants another.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You feel confident.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then insecure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Independent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then obsessed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Calm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Then completely irrational.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is no clean lesson.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No motivational quote.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">No five-step plan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Just instinct colliding with emotion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tove Lo finally found the scientific term for it in a book about cats.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u201cEstrus\u201d is
