Thompson's book is a well-researched, detailed, and utterly crucial-for-a-fan look at the brief career of Cream. Though a little light on analysis of the music itself, Thompson expertly tells the story of Cream with both previously-written interviews and his own research. I learned a lot that I didn't know before, and was particulary impressed with his evocative writing on the early '60s British R&B scene and snapshots of the era and players like Alexis Corner, Cyril Davies, and John Mayall. The only thing missing, due to printing timing, was a chapter on the London and NY reunion shows and what lead up to them (maybe for the paperback???).
