No Hiseman but John Marshall on drums who was at that time Nucleus' drummer and was about to join Soft Machine. Also played with Mike Gibbs as did Spedding (who left Nucleus to join Bruce's band).As great as that album is, his next, Harmony Row, is his masterpiece as far as I’m concerned. It’s just him on multiple instruments, Chris Spedding on guitar, and Jon Hiseman, drums. Brilliant keyboard playing, deep writing, throwing off the constraints of Cream.
Marshall and Bruce played together about five years later on Charlie Mariano's "Helen 12 Trees".
