a lot of different things going on with the Invisible Design albums on Tzadik. Solo bass. 2012 will see some solo shows, starting with one planned in NYC at Le Poisson Rouge on January 7 - part of Winter Jazz Fest.
Does Bill have any solo albums where he really showcases his bassplaying in a virtuoso sort of style, rather than dubby. Not sure how to ask what I'm asking for, but there is a video on youtube of him jamming with Derek Bailey, DJ Disk and Jack DeJohnette, and his playing on that is some of the most impressive I've heard from him... I'd like to hear more like it.
