For some reason bass players never seem to put out good solo albums, they all seem too much focused on "look what I can do" and once you get beyond that the material just isn't that great. I prefer great bass players in ensemble situations, i.e. Wooten w/Bela Fleck, Stanely Clarke w/Return to Forever, Les w/Primus, etc..
The only album I ever enjoyed listening too on a musical standpoint put out by a bass player is Stanely Clarkes If this Bass could only Talk.
