Although they shared some similar aesthetics and production techniques, British Psychedelia was quite different than its American counterpart. In general, British psychedelia was either more whimsical or artily experimental than its American counterpart, plus it tended to work within the pop song structure. This is not a hard-and-fast rule, however. No matter how many concise, pop singles they released, Pink Floyd still stretched out dramatically on stage, taking songs into uncharted territory with each performance. However, these general rules do more or less apply, particularly to the studio recordings of British psychedelic acts.
