In the late 1980s, Heaven would host two what would become legendary nights during the height of Acid House, Techno, and Breakbeat Hardcore rave culture. The first was "Spectrum" promoted by Paul Oakenfold and Ian St Paul, which ran on Monday nights between April 1988 and 1990, and the other was "Rage", a Thursday night running between October 1988 and 1993 which included DJs Fabio & Grooverider, Colin Faver, and Trevor Fung. Oakenfold brought in Jimmy Cauty and Alex Paterson (The Orb) as ambient DJs for his "The Land of Oz" nights at Heaven, club nights which Dom Phillips in "Mixmag" called "seminal". These chillout sessions in "The White Room", also involving Youth, heralded the birth of ambient house. Cauty's other band, The KLF, made their premier live performance at the Land of Oz in July 1989.
