I remember when this came out; I was in college at the time. I had no awareness of this group then (I was absorbed in acid rock and the Grateful Dead - hey, it was college!) but an acquaintance turned me on to this and I have loved it since.
This record (now CD) is an unsung prog-rock classic that's long been overshadowed by its more popular musical brethren. I do hear influences from SuperTramp, Emerson Lake & Palmer, and Pink Floyd. However, this is also a coherent, musically multi-layered concept album that packs an emotional punch and transcends its influences.
The general idea is that a space-traveling race journeys to a solar system, and encounters the wreckage of the planet Klaatu, a metaphorical stand-in for Earth. The only remnants are a laser-beam lighthouse adrift in the asteroid belt, manned by a single person. The disc is a musical account of the destructive fall of Klaatu's once-great civilization Politzania, and the space travelers' encounter with the dying lighthouse keeper.
The message resonates if you give it a chance. It also has stunning relevance today. If you don't see the similarities between Klaatu's fictional Politzania and Bush's America, then I have to assume you're A) a Republican; B) a musical snob. The tunes "So Said the Lighthouse Keeper" and "Hope" are probably among the most moving pieces of music ever to come out of the prog-rock milieu.
This disc will always have a place in my CD collection. I am so glad it's back in print. If you're interested enough to have read this review, you owe it to yourself to get this.
