Si Notting Hill era una zona dentro de otra zona que eran los 70, The Roundhouse, en Candem Town, era una suerte de piedra angular de la contracultura Británica, en ella, curiosamente, se presentó la revista International Times que, a su vez, era otro de los centros que hemos frecuentado estos meses para trazar este dibujo de la Zona, de los 70.
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, 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.
