You can hear buzz-heavy Southern rockers Alabama Shakes give their all on 'Hold On,' a charmingly earnest and passionate soul song that serves as the lead single from their debut album, 'Boys and Girls,' which dropped in April 2012. The rhythm section lays down a slinky groove perfect for guitarist Heath Fogg's winding riffs, but it's singer Brittany Howard's powerful pipes that give the band its direction: always moving forward, never holding back.
