& A Gilbey Ltd. In 1964 the premises were transferred to Centre 42, which prepared a scheme to convert the building into "a permanent cultural centre with a theatre, cinema, art gallery and workshops, committee rooms for local organisations, library, youth club and restaurant dance-hall". This was estimated to cost between £300,000 and £600,000 (£–£ in worth), and was supported by "well-known actors, playwrights, authors, musicians and others". In 1966 the Roundhouse became an arts venue, after the freehold was taken up by the then new Greater London Council. The opening concert was the 15 October 1966 All Night Rave, in which Soft Machine and Pink Floyd appeared at the launch of the underground newspaper International Times. During the next decade the building became a significant venue for UK Underground music events Middle Earth and Implosion. Many of these were hosted and promoted by Jeff Dexter. Other bands playing at the Roundhouse during this period included Gass, The Rolling Stones, Jeff Beck, The Yardbirds, Zoot Money's Dantalian's Chariot, David Bowie, The Sinceros, Graham Bond, Jimi Hendrix, Pink Floyd, Led Zeppelin, The Incredible String Band, Fleetwood Mac, Third World War, The Doors with Jefferson Airplane, Ramones, The Clash with The Jam, Elvis Costello, Elkie Brooks, Otis Redding, and Motörhead, who appeared at the Roundhouse on 20 July 1975.

Sets were built inside the structure, although the lack of proper soundproofing meant all of the dialogues had to be re-recorded. The building was used again in 1996 to film the promotional video for the Manic Street Preachers' single "A Design for Life" prior to the start of redevelopment. Promotional videos for the singles "No Matter What" by Boyzone (1998), "Handbags & Gladrags" by Stereophonics (2001), and "Burn Burn" by Lostprophets (2003) were also filmed there. A scene from the comedy film Smashing Time set in the revolving restaurant at the top of the GPO Tower was filmed there in 1967. In July that year the Roundhouse hosted the "Dialectics of Liberation" with (among others) R. D. Laing, Herbert Marcuse and Allen Ginsberg. The Roundhouse has also been used for theatre, and has had two periods of theatrical glory, with musicals such as Catch My Soul (1969). Under administrator George Hoskins, the first phase
