This release sees Jackmaster's always on-point Numbers label with their first reissue, and they've pulled off something quite special with this reissue of Pierre's Pfantasy Club's seminal "Mystery Girl (Set Me Free)". It's a full on piece of vintage analogue 303 jack, characterised by its synthesised slap bass and catchy-as-hell vocal. Considering this is vintage acid house, the 303 line is actually quite restrained, only drifting in briefly, but is made no less furious by the cut up vocals that see the track out. Up next, Numbers employ veteran UK producer Seiji to provide a "Bassrub" of the track. It's actually incredibly sensitive to the original, letting it do its own thing for the most part, forgoing his usual funky tempos, but cutting the vocals up further and adding some devastating subs that will blow out bass-bins everywhere.
