Harry Nilson was, as once said I believe by John Lennon, his favourite American group. When Nilsson harmonises with double or multi tracking his voice, there are few that can compare. This double CD album, featuring three original LP's, plus 4 bonus tracks show what a talent he was. Disc 1 features his first two albums, much of which I had heard before, whereas Disc 2, the Aerial Pandemonium Ballet album, is a re-make of many of the tracks from the former two albums. I'd not heard these versions before. Although I wouldn't say they are better or worse, it's just great to hear a new take on a familiar song. This double set will get a lot of plays.
