I do occasional solo bass gigs and really enjoy it Generally they've been at guitar clubs where people are quite open to instrumental music ( I've also been lucky enough to support Steve Lawson and Seth Horan where the audience are already bass friendly).
Ultimately music is music and if people listened more with their ears and less with their eyes, the instrument would probably be more widely received. Unfortunately, the recognised role of our instrument can be a hinderance as well as a great bonus. The bass player is always seen as the supportive one - "play your roots and don't get in the way" - so it can be a bit of an "unlearning" process to play the full arrangement, and also a bit of an unlearning process for the audience to accept it. The plus side is that bass players are often the ones who listen to the whole arrangement, not just there own part as the bass' role is vital in tying together the rhythm and harmony. As a result, bass players are on a good position to understand what parts of an arrangement are needed to make a piece work (and also why bassists often make great producers).
The resource for solo bassists sounds like a good idea
