Young Christian Sibthorpe, alias A1 Bassline, returns to Tighten Up Records to release a new single. For this occasion, the South Londoner moves away from the somewhat histrionic and fairground-ish hyper-bass that could be found on his previous productions and delivers two cuts with accelerated and nervous rhythms, but with a much darker and more severe counterpoint that wouldn’t sound out of place on a label like Swamp 81. Today we give you the video of “ Shockheaded”, in which we can see how London kids leave their mark on walls, trains and other urban property. Bass, tagging and train bombing for the hooded youths. By the way, did you hear the recent PlayGround podcast?
