It was way back in 1994 when the Black Science Orchestra - AKA Ashley Beedle, Uschi Classen and Marc Woolford - first released the Altered States EP. As this timely reissue on Groovin' proves, it remains a benchmark of British deep house. The EP is arguably most famous for the Wood, Brass & Steel-sampling brilliance of "New Jersey Deep" - a track that should reside in any house-head's collection - though the similarly-minded laidback positivity of "Philadelphia" (whose swinging drums, toasty electric piano chords and rising synthesized horns pay hearty tribute to Philly Soul) pushes it close. The EP also includes a tasty "Drumadelphia" version of the latter track for DJs who like to play around with percussion, while "Vario (SOS)" is an organ-rich trip into hazy lounge music territory.
