On What’s Going On, the first EP in their series The Spacy Saga, Jupiter4 Records served up a quartet of driving house tunes that came with serrated edges. They’ve managed to top themselves on Don’t You Wanna Know? / The Spacy Saga Vol. II. Not only are these tunes are tougher, more rugged, their beats pushing on through house to industrial techno and Detroit-school electro, but there are also more of them here - six to What’s Going On’s four. Techno fiends will be sated by pummeling tunes from Drvg Cvltvre and Jack Roland; those of you who like their beats more Drexciyan should slam down the entries from Aquatronics, Cybereign, Datawave and Psynote.
