During the mid-to-late 1970s disaffected European psych-rock musicians, inspired by the music of Arnold Schoenberg, Kurt Weill, Sun Ra, Olivier Messiaen, and Soft Machine, as well as by the politics of the radical left, formed a loose collective of bands that came to be known as the Rock in Opposition movement. Spearheaded by bands like the UK's Henry Cow and Belgium's Univers Zero, the movement produced dense, challenging, and at times startlingly beautiful music that used surreal and dadaist lyrics to advance a message of anti-fascim, anti-capitalism, and anti-consumerism. Tune into Polyphonic Perversity tomorrow from noon to 2pm to listen to the music of Rock in Opposition movement and the musicians that continue to uphold the tradition today.
