New releases last four weeks: Techno (All)

Review: Last year, the Hartnoll brothers gave their debut album, 1991's 'Green Album' (officially simply titled Orbital) the deluxe reissue treatment, offering an expanded quadruple CD edition backed with a detail-packed hardback book. They've now moved on to its similarly superb sequel (the 'Brown Album') from 1993. It gets a similar treatment, with a freshly remastered version of the original album (CD1) being joined by two discs of single versions, B-sides, remixes and 'Peel Session' cuts (including legendary Underworld and Psychik Warriors Ov Gaia takes on 'Lush 3', and the duo's own originally US-only extension of 'Impact'), and a fourth CD containing a previously unreleased live recording from the Limelight in New York in 1992. Oh, and a fine hardback book telling the story of the album. An early Christmas present for Orbital fans!

Review: There's a strong argument to be made that 1993's Orbital II, popularly known as 'The Brown Album', is the Hartnoll brothers' finest single album - a sublime fusion of bustling breakbeats, heady vocal samples (many provided by then unknown vocalist Alison Goldfrapp), twisted acid lines, memorable melodic motifs, and rush-inducing breakdowns. Here reissued in remastered and expanded form, the set - which includes fan favourites 'Lush 3', 'Halcyon' and the superb 'Impact (The Earth is Burning)' the album sounds as fresh and forthright as ever. This time round, it includes a second CD featuring key cuts from the two-part 'Raddicio' EP (including two takes on the Scott Walker-sampling 'The Naked & The Dead') and superb revisions of Lush 3 by Underworld and Psychick Warriors Ov Gaia.

Review: After almost three decades, Kompakt Records is set to deliver its' 500th release - a ridiculously impressive landmark that few electronic labels have previously achieved. To mark the occasion, the Cologne-based imprint has decided to deliver an anniversary compilation featuring (mostly edited) versions of some of its most iconic club hits, underground gems and early obscurities. It does a terrific job in explaining, via music, the label's contribution to European electronic music culture - think 'maximalist' minimal, off-kilter tech-house, ambient pop, synth-heavy hypnotism and twisted, off-kilter nu-disco. Naturally, all of the label's most significant contributors are present (Superpitcher, Justus Kohncke, Robag Wruhme, Gas, The Orb, Jurgen Paape etc), alongside artists you probably didn't realise had released on the label.
