Though a cool September air was chilling down one of Milwaukee’s steamiest venues, Sound Tribe Sector 9 still managed to bring the heat to The Rave with their wall of psychadelic sounds and electronic fusions. With artist Kris D. joining the band onstage for a round of “live painting,” the stage was set for an evening of creative exploration and artistic expression.

Opening with the funky and robotic “One a Day,” STS9 wasted no time in stirring up the eager crowd for the two-set marathon. Zach Velmer’s relentless drumming was like that of a heartbeat out of control, and at times it seemed that his set would simply explode under the furor of his sticks.

“GLOgli,” an electronically driven monster that has quickly become an epic STS9 concert staple, was one of the evening’s most ambitious and defining moments. Bassist Dave Murphy and guitarist Hunter Brown traded their respective instruments for laptop computers, looping beats that were both sharp as knives and loud as thunder.

The second set was rounded out with tunes such as “Be Pulse,” a swelling and captivating piece that featured the reverberating tones of keyboardist Dave Phipps, as well as Brown’s climbing guitar. “Blu Mood” closed the evening in a meandering frenzy, leaving the crowd exhausted, yet still chanting for more.

The art that was created that night, both with the stroke of the paintbrush and the spray of the electric painters themselves, was etched deeply into the easels of the minds of those in attendance. It was a gallery that will not soon be forgotten.
