Cream live is so good. Clapton really shows his great blues, Jack Bruce shows us his great voice range and Ginger Baker's great jazzy rocky drum style is also present. The studio version of N.S.U is almost three minutes, while the live version is over ten minutes. Sleepy Time Time shows how well Cream can do a slow blues song. Rollin' and Tumblin' is really a great song and Bruce's harmonica work is awesome. I highly recommend this CD for a cream fan, a blues fan or a 60' 70's music fan.
