What bassist-led musical endeavours are there that don't make music that's utterly risible?
John Patitucci, Dave Holland (one of my favorite groups, period), Charles Mingus and depending on your feeling, Jaco Pastorious (I am a passing Jaco fan).
Don't forget about Serge Koussevitzky.
ETA: Thanks to this thread, I have been listening to McCoy Tyner all night. Maybe this is a good thing.
