Much more familiar with his work in the late '60s/early '70s, essentially pre-Colosseum. I like him with the pianists, and he's solid on the Jack Bruce Things We Like LP. Maybe he took a turn for the worse later.
That Jack Bruce is nice indeed - but the way he played with Colosseum or the United Jazz & Rock Ensemble bores me.
Check out his playing with Neil Ardley/New Jazz Orchestra and the Mike Taylor Trio. Excellent !
Much more rock-oriented later on, although I quite like his playing with Barbara Thompson (Mrs Hiseman) in 'Paraphenalia'.
