This could be bassists, or recordings, or off topic, so feel free to move at will! I caught John Mayer on The Tsunami aid show a few weeks ago. I heard his stuff on the radio and thought it was pleasant and didn't annoy me. But he totally smoked on that show. He covered Axis Bold As Love. It was absolutely killer. So I went out and bought a couple of his cds, and man, the bass playing on his first hit, the one about running through his high school, you can't hear it on the radio, but the bass player is ALL over the neck. Jumping octaves, it reminded me of bass playing from the 60s. The Ox, the dude from the Kinks, Sir Paul. Really meaty bass work. If you never paid attention before, like me, and you're at a good stereo, when it comes on, stop what you're doing and listen.
