In 1974 Led Zeppelin staged a media party at Chislehurst Caves in Kent, to launch their Swan Song record label and release the label’s first album, Silk Torpedo by The Pretty Things. Dominated by extreme performances and scantily clad (if at all) female models, Zeppelin’s launch was extreme, lavish, hedonistic, media heavy and excessive. 40 years later, inspired by this event and the format and ambitions of media and industry parties, artist Cushla Donaldson created Supergroup, a performance and installation event at The Audio Foundation, Auckland.
