In 1991 the Glasgow band Primal Scream released one of the all time groundbreaking dance-influenced rock records, Screamadelica. It was a breakthrough album for lead singer Bobby Gillespie and company, winning the first ever Mercury Prize in the UK. Combining house music and R&B with the band’s indie rock roots, Screamdelica remains to this day one of the best and most acclaimed albums from the 90s, and on songs like “Come Together,” “Movin’ On Up,” and their cover of Roky Erickson’s “Slip Inside This House,” Screamadelica turned rock and roll inside out. While Screamadelica remains their legacy, Primal Scream has since released an impressive body of work, and their 2013 release More Light is perhaps their best release since Screamdelica. Philly fans will get to see the band in action when they play the TLA on Friday, May 9th. Go here for tickets and more information. Below, watch a BBC documentary on Screamadelica, and listen to “It’s Alright, It’s OK,” from their recent album.
