With an assault of Sabbath-esque guitar riffs, ‘70s rock muscle, and alluring vocal harmonies, it's little wonder that this British rock trio is heralded as rock ’n’ roll saviors. Bluesy, bold, and best with the volume cranked, Band of Skulls' 2012 Sweet Sour is a hook-laden tour de force. Don’t miss their performance at iTunes Festival at SXSW on March 13.
