Aussie rockers Wolfmother have broken up. The Grammy winning band played their final show last weekend at the Splendour in the Grass Festival in New South Wales .

"Wolfmother has announced the resignation of bass/keyboard player Chris Ross and drummer Myles Heskett effective immediately" read a statement released Wednesday. "Singer/guitarist Andrew Stockdale now plans to find other musicians over coming months and to then begin making a new Wolfmother album. Wolfmother toured the world virtually non-stop through 2006 and early 2007 on the back of their acclaimed self titled album. Longstanding frictions within the group then lead them to take an extended break during the second half of 2007 to consider their future."

Following the Splendour show, Ross revealed his decision to quit the band over "irreconcilable personal and musical differences." Meanwhile Hesket has left the band "rather than continue as part of a changed line-up." The departed musicians have been working together on new material for some time and intend to embark on a new project.

The now-splintered group asked Wolfmother fans to "please understand that in spite of their best efforts over a long period of time, they just could not find a harmonious way to work together."
