Bass/keyboard player Chris Ross and drummer Myles Heskett have resigned, effective immediately, leaving just singer/guitarist Andrew Stockdale.

A statement on the band's website says Stockdale plans to find other musicians and make a new Wolfmother album.

''Wolfmother toured the world virtually non-stop through 2006 and early 2007 on the back of their acclaimed self titled debut album,'' the statement said.

''Long-standing frictions within the group then led them to take an extended break during the second half of 2007 to consider their future.''

The final straw came at the weekend where Wolfmother headlined the Splendour in the Grass Festival in Byron Bay.

''Following that show Chris Ross decided to announce that he was leaving the band due to irreconcilable personal and musical differences,'' the statement said.

''Myles Heskett has also decided to leave the band rather than continuing as part of a changed line-up.''

Wolfmother's self-titled debut album sold more than 1.3 million copies and received multiple ARIA Awards and a Grammy Award. AAP
