During the late 1960s, the press labelled Pink Floyd's music psychedelic pop, progressive pop and progressive rock; they gained a following as a psychedelic pop group. In 1968, Wright said: "It's hard to see why we were cast as the first British psychedelic group. We never saw ourselves that way ... we realised that we were, after all, only playing for fun ... tied to no particular form of music, we could do whatever we wanted ... the emphasis ... firmly on spontaneity and improvisation." Waters said later: "There wasn't anything 'grand' about it. We were laughable. We were useless. We couldn't play at all so we had to do something stupid and 'experimental' ... Syd was a genius, but I wouldn't want to go back to playing 'Interstellar Overdrive' for hours and hours." Unconstrained by conventional pop formats, Pink Floyd were innovators of progressive rock during the 1970s and ambient music during the 1980s.
