Pledging allegiance to thick, throttling fuzz guitars, primal psychedelia, and thundering rhythms, the 21st century rock revivalists Wolfmother split the difference between the classic sludge of Black Sabbath and the retro-garage rock of the White Stripes. Led by guitarist/vocalist Andrew Stockdale, the power trio came storming out of Sydney, Australia in 2006 with a self-titled debut that generated international hits in the form of "Woman" and "Joker & the Thief." Although they had some stumbles following up this initial success -- bandmembers came and went, leaving Stockdale the sole original member -- their subsequent albums Cosmic Egg (2009) and New Crown (2014) played to a cult devoted to their heavy, riff-oriented rock.
