We thought we knew what to expect, walking into the Pour House on Friday night for the first of Boombox’s two weekend shows. The bright lights, pulsating beats, and sweaty gyrating bodies are all too familiar to Chucktown music lovers. But there was something about this concert that gave it an extra oomph. We arrived after Eliot Lipp, who opened for Boombox on Friday, had finished playing his set and walked outside. The usual rave kids puffed away on the PoHo patio with hoards of others boozing, waiting for the show. Soon enough, the music began, and fans trickled inside to find a place to post up by the stage. We hung out in the back booth for a while, delighting in the vibrating bass, as we watched a happy blonde girl bounce around with liquid grooves. On stage, singer Zion Rock Godchaux, guitar in hand, was wearing his signature purple feather bucket hat, with a boa dangling from his microphone. Producer Russ Randolph stood behind him on the turntables. The pit was a beautiful mess. Flashing colors moved around like hexagonal Rubik’s Cubes. A pair of women made out with each other so intensely they fell on stage — all the while being groped by a sea of sweaty, dancing dudes. The music ripped from start to finish. It was a night of madness, as Boombox rocked and settled everyone’s mood.
