Funky/fusion jazz with heavy base emphasis....

Brand X and Jeff Berlin albums have wonderful bass. You may also want to try Tribal Tech albums such as Dr. Hee, Illicit, and Spears. Also solo recordings from Chad Wakerman and Laurence Cottle are quite heavy in the bass registers, if you like jazz fusion. Lots of these recordings are hard to find but Audiophile Imports can help you find most of them.

You could try: Music Revelation Ensemble very funky power fusion, PBD with Jaco on bass,Stuttgart Aria with Bireli Legrand on guitar and Jaco on bass, Essence (featuring Jaco) Last Flight.....These won't be easy to find but they might satisfy your jones for power funk jazz fusion, for a little while anyway.

I forgot to mention Stanley Clarke. Several choices are good but for power bass fusion the first one I like the best. Several Tony Williams Lifetime discs might work for you also as well as a couple of Tony Levin titles.
