The six year span of Pink Floyd's career between Piper at the Gates of Dawn and Dark Side of the Moon is a meandering, often treacherous stretch of road. That's not to say that it didn't show some signs of promise, and here and there, occasional glimpses at the brilliance that was on the horizon. Commissioned to record ambient sections of soundtrack music for Michaelangelo Antonioni's film Zabriskie Point, the band took full advantage of their studio allowance to not only record a wealth of material that would signal a shift toward pastoral folk of Meddle and Obscured By Clouds, but to demo rough sketches of tunes that would turn up on Dark Side of the Moon a couple of years later. With the effects of their acid-drenched Syd Barrett period still lingering, it's not surprising that a few brief slices of self-indulgence pop up here and there, but overall The Complete Zabriskie Point Sessions is an exciting listen, if not a completely captivating one from end to end. Had the fat been trimmed and a few overdubs thrown on for good measure, these sessions would have resulted in their first great album of the post-Barrett Floyd. On it’s own terms, it’s still an essential document in tracing the evolution of one of psychedelic rock’s all-time greats.
