This album is simply amazing. What makes it so unique is how the whole album is just one 40-something minute track except for the fact that it's split up into two parts (one for each side of the original LP release, although the first CD pressing of the album had both parts as one track). The song is also known for its random tempo changes. The album is a satire of bands like Yes and Genesis, as frontman Ian Anderson did not like that the band's previous album "Aqualung" was called a concept album when it wasn't, and decided to spoof the concept album thingamajig with this album. This is one of the best albums of all time. I also like the album "Crest Of A Knave" XD
