Australian rock band Wolfmother broke through in 2005 with their self-titled debut album, on which the trio breathed new life into classic 70s hard rock—the fact that frontman Andrew Stockdale's voice sounds a bit like Ozzy Osbourne's certainly helps. Songs like "Woman" and "The Joker & The Thief" are now staples in every rocker's playlist, but don't overlook the rest of Wolfmother's catalog. Their debut album was followed by excellent albums like "Cosmic Egg" (2009, featuring the smash "Sundial"), "New Crown" (2014), and their latest effort (also tonight's motto): "Rock Out!"
