This is a very early blue print of the band's more well-known hits that would come later as the result of Ummagumma being the start of Pink Floyd's experimental phase that would continue on with Atom-Heart Mother (1970) and Meddle (1971). Here the band began early experimenting to test their own music individually shown by the second disc of Ummagumma to see where it stood alone as compared to playing together with each member having their own signature compositions. Of these compositions by each band member the ones that made the album so strong musically to me were Rick's Sysyphus pts 1-4, Roger's Grandchester Meadows, Dave's The Narrow Way pt 3, and Nick's The Grand Vizier's Garden Party pt 2: Entertainment. The live album the comprises the first disc of Ummagumma is also very beautifully sounding with the haunting screams on the live version of Careful With That Axe, Eugene and the live version of Astronomy Domine which is almost identical to the original version that appeared on the band's 1967 debut album The Piper At The Gates Of Dawn While Syd Barrett was the principal singer and song writer for the floyd. All in all I would say Ummagumma is a must have and important album to own by any Pink Floyd fan because it not only has very lovely and unique music on it but it also was the early experimentation where the band saw what worked and what didn't and would later lead to more experimentations in the early 70's that would eventually spawn and evolve into masterpieces such as Dark Side Of The Moon, Wish You Were Here, Animals, and The Wall. Ummagumma is an excellent Pink Floyd album that deserves more credit than it gets.
