With Steve O'Sullivan's back catalogue getting re-released, it is timely that attention also shifts to Mark Ambrose. The UK producer was one of the most innovative in the UK tech-house scene, and as "Shooting Stars" demonstrates, he is the master of creating bassy, murky grooves. Based on a tracky rhythm and vicious snares, when the tripped out bassline kicks in, it's hard to imagine any speaker system being safe. The remixes are of a high quality too; Ambrose's own version imbues the arrangement with a disco undercurrent, while Ben Sims toughens it up and adds eerie acid lines. Best of all though is fellow traveller Aubrey's take, with its rumbling bassline and visceral 303 licks.
