Ummagumma - Pink Floyd

The first albums of Pink Floyd are closer to experimental rock and Jethro Tull than to their most famous works like The Wall or The Dark Side of the Moon.

The band hate their earlier albums, including Ummagumma. The only song of this production that has been recycled recently is "Astronomy Domine," and mostly as a tribute (one more) to Syd Barrett.  Ummagumma, like The Piper at the Gates of Dawn, is more valuable as a testimony of psychedelia than as a piece of music. There are much better experimental rock bands, including Jethro Tull, King Crimson, or even Sigur Ros, if you push it too hard.

Ummagumma must be listened to as an experiment, a work in transition.
