Wolfmother have pulled out of some dates this summer, including some biggies like Download and T-In The Park with no more of an explanation other than “due to illness”.

The Hives are set to replace them at this years Hard Rock Calling in Hyde Park, While Killswitch Engage plug the gap for the organizers at Download Festival.

With no other dates for the band announced this side of the pond, and the updates not even on the official website yet (true upon publish June 2nd 2010)  it makes you wonder whether or not the band are taking some needed time out and going through get another line-up change.
