Dance pop duo Matt and Kim showed up a little later at the Fader Fort opening event to a larger crowd, but far from the packed house the space will be even tomorrow. Drummer Kim thumps out the rhythm with manic energy, a devilish smile on her face the whole time. Singer/keyboardist Matt leads the mayhem egging the crowd on for furious dancing. The results are clearly joyous, but it’s a little disheartening to see how much they rely on a laptop to cue up backing tracks. At one point it broke, so the set stalled, prompting Kim to tell a story of SXSW drunkeness from the band’s past. We first saw them at a small lot party back at SXSW 2006. No laptop was needed then to rock the crowd.
