PSO is from from Lemon Grove, Ca - a neighborhood in east San Diego. Originally starting in 2012, PSO quickly began to pick up steam. They are the epitome of what skateboarding and punk rock embraces. They skate before the show, and then put on a consistently wild stage performance. Imagine RKL mixed with Bad Brains, and you have PSO. They've shared the stage with heavy hitters such as Madball, Turnstile, Angel Dust, Angelic Upstarts, Bane, and JFA just to name a few.
