Came across this. Fastest Bassist at 660 BPM - Jayen Varma : Free Download, Borrow, and Streaming : Internet Archive
He actually sounds pretty good considering how fast is playing but he's not playing at 660 beats per minute, that's just the metronome.
No mention yet of Stanley Clarke? During the many shows that I saw him perform at, and many of his recordings, I would say he ranks right up there. And that’s with hands that can palm a Volkswagen Beatle!
I got a TrailBlazer SS up to about that with two basses, and SVT and an 810 cab in it. Fast fingers don't matter to me. I can do fast licks. But can those fast licks move people? That's all that matters.
