You'd never heard of him but you had heard him.
That goes for quite a few names mentioned in this thread, tbh. I mean, I couldn't have told you the name of the bass player on, for example, Paul Young's Wherever I Lay My Hat, even though I've always loved that record and its iconic bass line. When it came out, I was 10 years old - I wouldn't have cared who was in the band.
That sample.
I was into Billy Cobham in the 80s, so it kind of pissed me off when Massive Attack pinched the line.
Not being familiar with Billy Cobham's work, I never even realised it was a sample. Listening to Spectrum right now though, and loving it. One of the great things about threads like this is filling these gaps in my knowledge.
