Keyboardist/bassist Chris Ross and drummer Myles Heskett have exited Australian rock act Wolfmother after "longstanding frictions," but frontman Andrew Stockdale says he will continue the group with new members.

"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," reads a statement from Universal Music Australia.

Wolfmother exploded onto the scene with its self-titled 2006 debut, which has sold 517,000 copies in the United States, according to Nielsen SoundScan. It launched the rock radio hits "Woman" and "Joker and the Thief." The former song won a Grammy for best hard rock performance.

Following extensive touring in support of the album, Wolfmother went on hiatus late last year, emerging in April to roadtest new songs. But band member tensions remained, and following last weekend's appearance at the Australia's Splendour in the Grass festival, the decision was reached to split up.
