One of the founding fathers of what we refer to as Dubstep, Caspa, led the Dub Police tour at the show in downtown San Francisco at 103 Harriet. The show featured fellow artists Subscape and Trolley Snatcha although Trolley Snatcha was replaced by Matty G after he failed to appear for reasons unknown. Anyone who caught onto pre-Skrillex Dubstep knew what this was all about. The show featured UK Bass in its entirety, which focuses primarily on the lower register, sub bass elements that defined the Dubstep in the UK when pioneers Skream, Benga, Caspa, and Coki began experimenting with Garage some years ago before the higher and more extreme frequency sweeps of today’s heavy, American sound took over. Although Trolley Snatcha did not appear, the crowd was still riveted with the dark and deep bass that resonated throughout the room during Caspa’s performance. Subscape’s eerie, vibrato based melodies pulsating through the club with an intense force that could only be described as ominous, seemed to cause ripples in the crowd from the audio source. The energy was high and the tempo was low. The crowd was served filth, which is a dish best served cold and in the end they seemed to be well filled. Hats off to the crew on the Dub Police tour for their excellent performance.
