|Jazz Upright Bassists I find Influential.|
Anything these cats play on is great, so if you're a bassist or just enjoy the genre in general, get into these guys/gals if you haven't already heard them. Any album, whether it's lead by them or if they accompany is worth checking out. There's a lot that I've left out, but this site only has a select few of these artists. I can recommend more in the comments if needed.
