The discography of Australian hard rock band Wolfmother consists of four studio albums, four extended plays (EPs), eleven singles, twelve music videos and one video album. The band have also contributed to two soundtracks and one tribute album. Wolfmother were formed in 2000 by vocalist and guitarist Andrew Stockdale, bassist and keyboardist Chris Ross, and drummer Myles Heskett. After signing with Modular Recordings and releasing their self-titled debut EP in 2004, the band's debut full-length studio album, also titled Wolfmother, was released in Australia in 2005 and reached number three on the Australian Albums Chart. The album was released internationally the following year, selling over 1.5 million copies worldwide by 2009. In August 2008, Ross and Heskett left the band due to "irreconcilable personal and musical differences". Wolfmother returned in early 2010 with a new lineup featuring bassist and keyboardist Ian Peres, rhythm guitarist Aidan Nemeth and drummer Dave Atkins. The follow-up to Wolfmother, Cosmic Egg was released in October 2009, again reaching number three in Australia. (Full list...)
