Their final album, "Time Of Change" (1974), was their crown achievement in terms of musical dexterity, displaying neckbreaking keyboard pyrotechnics. Here The Trip used a very broad range of influences, from conventional music to avant-garde. Opus Avantra had a similar basic idea, but with completely different results, musically speaking. Their complex jigsaw never hung well together, whereas The Trip's work was more convincing. Most impressive was "Rhapsodia" (20:00), in the top class of Italian keyboard-driven progressive rock.
