It comes ahead of an as-yet untitled second album, the follow-up to the Modular-signed act's 1.5 million selling self-titled debut from 2006.
In early April, they will record the remainder of the album in L.A. with acclaimed producer Alan Moulder (My Bloody Valentine, Smashing Pumpkins, Nine Inch Nails). "It's full steam ahead with a view to get a record out for the fourth quarter," Wolfmother's manager John Watson tells Billboard.biz.
The group performed "Back Round" last Friday as the final act of the Vodafone MTV Australia Awards in Sydney. The band is encouraging fans who download the track to donate a fee to the Red Cross Victorian Bushfire Appeal.
Originally a three-piece, the band imploded in the latter part of last year. Frontman Andrew Stockdale resurrected the band with a new line-up and made a coming out party of the Sound Relief bushfire benefit concerts on March 14, where a four-man Wolfmother played at both the Melbourne Cricket Ground and Sydney Cricket Ground legs.
