Australian rock group Wolfmother have shocked fans by releasing a new album, a year after they allegedly disbanded.

The group took to Facebook.com on Monday (24Mar14) to announce the release of a digital record entitled New Crown.

Fans posted a host of messages expressing their surprise at the move, which comes 12 months after frontman Andrew Stockdale insisted Wolfmother was over last April (13).

It is the rockers' third album, following up 2005's Wolfmother and Cosmic Egg in 2009.
