Tom Warrington seems to have disappeared in recent years. I don’t know if he realises how unique he is in terms of playing jazz on electric bass, I’m not a Buddy Rich fan at all but I listen to these old recordings for bass inspiration quite often.
His albums (where he plays upright) are not available online anywhere now. I’m glad I have them all on cd, Back Nine is one of my favourite jazz albums. He had a few other jazz recordings without Buddy Rich where he plays his fretless P, all discontinued and difficult to find.
