I'm feeling the need to experience more jazz style music lately and am just wondering if I could get some good jazz grooves to listen to. Is there anything that I simply must listen too? What is some of the better jazz songs with good bass playing in them? Not necessarily busy, but just holding the groove and supporting others, maybe with a few tricks here and there. Also I know tone is very subjective, But Who are some of the jazz bassist that always seem to have their tone spot on for each song they are playing?
