Back catalogue: All genres

Review: To mark the passing of three decades since he established the now iconic Environ imprint, Morgan Geist has decided to reissue the label's long-deleted debut 12" - a solo EP that was just his second release. At the time, Geist had yet to develop the disco-leaning but naturally synth-heavy trademark sound he's become renowned for. Instead, he was investigating the stargazing potential of Detroit-influenced techno and jacking-but-spacey house. Check first the lightly bleep techno influenced excellence of 'Sands' and the more driving, upbeat and jacking 'Airpour', before diving deeply into the percussively rich deep techno wonder of 'Smear'. To complete the package, we get a suitably cosmic, pitched down ambient techno revision of the same track by The Connection Machine - back then a duo who had just released a fine EP on Planet E.

Review: GU (which is of course an alias of Chicago favourite Glenn Underground) is back with a 20th volume of his Classiques series. It once again finds him adding his own special studio magic to come stone-cold classics from the funk and disco world. First, he flips Le Cop's 'Move Your Body' into a funky percussive sound with steamy vocals. Then Machine's 'Marisa' becomes a jazzy and expressive sound with busy leads and funky guitars and Loose Joints's 'Tell You Today' is a wild horn-led sound with a busy arrangement and pumping drums. Last of all are the sunny and soulful sounds of The Isley Brothers's 'Hurry Up & Wait' with cool house drums.

Review: Prog rock giants Genesis caught in live action in London in late 1973, a mere month after the release of their Selling England By The Pound album. This is what many claim to be the band at the height of their powers, with their highly celebrated Foxtrot album not long behind them, hitting their experimental, quirky time signature peak and with Peter Gabriel still commanding the microphone. Opening with the thrusting 'Watcher of the Skies', Tony Banks' keyboard stabs almost rave-like in their stabbing power, they hurtle through tracks from the latest offering ('The Cinema Show', 'Battle of Epping Forest' and the anthemic 'I Know What I Like') alongside Nursey Cryme album fan favourite 'The Musical Box' and a version of the epic 'Supper's Ready' that stretches to nearly 24 minutes here. 'More Fool Me', meanwhile, which sees drummer Phil Collins step forward to sing its folksy, almost Bee Gees-like pop strains, points to where the band would be in a handful of years' time.
