I just added an interesting little CD to my collection "Jeff Beck's Guitar Shop". The lineup is Jeff of course with Tony Hymas on keys and synthesizer and Terry Bozzio on drums and percussion. No bassist. This is a great jam CD for a bassist because there is only a bare minimum being pumped out by Hymas. You can easily catch the groove and work along without clashing with a recorded bass line. And of course Jeff's work is utterly amazing, even more so for a guy that doesn't read music and essentially does everything by ear.
