For a band named after an angry outburst, Fitz And The Tantrums seems pretty content. The up-and-coming L.A. band just filmed an episode of Guitar Center Sessions set to air tomorrow, Friday, June 14 on DIRECTV’s Audience Network (channel 239). During the show, the group played tracks from its newish record, More Than Just A Dream, as well as tracks from the group’s 2010 debut, Pickin’ Up The Pieces. Below, The A.V. Club has the premiere of a clip of the group playing “The Walker,” one of the tracks off the more recent LP. It’s kind of a barn burner, so buckle up.
