The preeminent promoter of Austin’s “sound of our town” put its money where its radio frequency sits on the dial (98.9) this summer with huge, free, community gatherings for White Denim and Moving Panoramas that net some 10,000 locals combined. Local synth-pop duo Zettajoule, Meggan Carney and Matt Sheffer, and rapper/looper SaulPaul now encore. Face painting opens festivities at 5:45pm.
