I can't add much more after what "Gentlegiantprog" has said. I think this is the last Gentle Giant masterpiece. By the days it was released, however, many prog music listeners actually thought that it was a bit disappointing if compared to its predecessor Free Hand in the creative department. 1976 was a year of skepticism for (not only) prog rock aficionados; everything seemed to be done, and all those magnificent albums like Dark side of the moon, Wish you were here, Brian salad surgery, The lamb lies down on Broadway, Red, Aqualung, Fragile, Close to the edge, Free Hand, etc. were going to make any further effort to be judged very strictly. And it was true that many bands were living difficult moments because of personal changes and/or creative crisis. Time has made its work, nevertheless, and the perspective of all these years allows us to appreciate the artistic value of this breathtaking album.
For those who are new to Gentle Giant, I would say that for some reason I don't know, this band never was as massively known as, for example, Pink Floyd or Genesis, while being in the same league in its own right. It would be easy to say that Derek Shulman is quite similar to Peter Gabriel and the band's music is a mix of Genesis, Yes, King Crimson, Jethro Tull and Frank Zappa with some extravagant or weird additions like strange and changing time signatures or a capella passages. But that would be too far from reality: these guys were master musicians with their own bold and original ideas, and an unique way of approaching rock music. Don't miss them.
