Trevor Jackson continues on plundering the vaults of classic genres of yesteryear. Following up the sterling effort of the Metal Box series of industrial and EBM classics, he now gathers the very best of Adrian Sherwood's seminal On-U sound imprint for this extensive compilation. All the usual suspects are here; Dub Syndicate with "Over Board", African Head Charge's "Stebeni's Theme" (amongst others) and how could we not forget Tackhead, who appear with the heavy "Now What?" Also appearing are Keith Le Blanc, Mark Stewart & The Maffia and Jackson's own Playgroup project plus many others, covering the imprints' illustrious history over three LPs. Essential listening.
