Across the last 90 minutes of his closing set, Om Unit moves with unmistakable emotional fluency through dubstep classics, bleep pressure, contemporary club foundations, unreleased edits and his own idiosyncratic productions. Caspa & Rusko-era nostalgia, Ability II’s “Pressure Dub,” Gaszia’s “Taste,” deep bassweight, breakbeat lift and rave euphoria all pass through the mix with class, warmth and soul.
