Womp, Womp, Womp. Wobbling bass speakers. Giraffe, zebra and furry-headed costumes. Sweat-dripping fans hanging over the balcony railing. Front-row heroes bouncing with their hands in the air. Freaks dancing on tables, chairs, anything wide enough to stand on. Lights. Video mashes. Hip-hop. Metal. Funk. This is Bassnectar. Yet there’s more to it, than a massive sound, a beat-freak following and out-of-control performances.
