Before acid house, Scotland's Primal Scream were your average, jangly psych-rock act. Then rave hit and Andrew Weatherall signed on to produce their third album, Screamadelica, and a generation's collective mind was blown. Their roots are evident in the Stones-style blues rock of "Movin' On Up," but the '60s quickly melt away as they dive into house beats, synth bleeps, dubbed-out remixology, and the mind-bending chillout bliss of "Higher Than the Sun" and "I'm Comin' Down." Dancing in muddy fields would never be the same again.
