Combining swirling psychedelic rock with hardcore hip-hop rhythms, the Shamen were one of the first alternative bands to appeal to dance clubs as much as indie rockers. Comprised of Colin Angus, Peter Stephenson, Keith McKenzie, and Derek McKenzie, the Scottish quartet had its roots in the early-'80s neo-psychedelic group Alone Again Or. The Shamen officially formed in 1986 and released their first album, Drop, the following year. Drop was filled with varying guitar textures, recalling many late-'60s rock groups. After the record's release, Angus immersed himself in the emerging acid house/hip-hop club scene, which prompted the departure of Derek McKenzie; he was replaced with William Sinnott, who helped reshape the band's sound into a dense, rhythmic pulse that relied heavily on samples, drum machines, and loud guitars. The band debuted their revamped sound in 1988 with a stage show that featured sexually explicit visuals along with impassioned political rhetoric. During 1988, Peter Stephenson and Keith McKenzie departed, leaving Angus and Sinnott to perform as a duo.
