It's hard not to feel that the Scratch Perverts' huge success is due in part to one of the most seductive stage names since the birth of the Rolling Stones. Frankly, it's a misnomer. Anyone expecting a turntablism masterclass tonight will be disappointed: there's only the most perfunctory demonstration of the Perverts' much hyped vinyl gymnastics. And, in truth, there's really nothing very perverted about these guys. Whether in London superclubs or Scottish student unions, the Scratch Perverts serve up good, solid sets, competently mixing house, hip hop and drum 'n' bass, and always—but always—remembering to include House of Pain's functional crowd pleaser 'Jump Around'. Eye-popping it ain't.

Local MC BZ's vocal dexterity has made him a fixture on Edinburgh's jungle scene; but he looks lost here without the hulking frame of partner Tonn Piper beside him, his sporadic outbursts adding little to the Perverts’ workmanlike opening hour of electro. Still, the reversion to drum 'n' bass with an hour to go sends a ripple of excitement through the crowd, and for half that time all hell breaks loose. Thereafter, the evening conspicuously winds down, the Perverts doing little to maintain the musical momentum as they trawl through their jungle collection. By the time BZ starts handing out posters during the final tune, the pace is slow enough for every recipient to roll their present up neatly for safe keeping.

For all the lack of inspiration, it's a more-than-enjoyable performance from a team of undeniably accomplished DJs, and fantastic value at £6. The Xplicit boys have excelled themselves in finding a loyal market for drum 'n' bass far from its southern heartland and, for all the upturned noses, have found in Potterrow a venue whose strong sound system and sizable dance floor make it a decent choice for this breed of event. The arrival this Friday of goblin-faced turntablist DJ Hype should more fully satisfy those in search of a dirty dose of scratch perversion.
