My long-time bass player in my sax-keys-drums-bass quartet had to cancel out just before a gig recently. He’s not as good as we’d like, so we decided to play the gig with (my) left-hand bass instead of dredging up a replacement. What a blast! We were able to play, on the fly, intricate and interesting interludes, backgrounds, etc., that sounded orchestrated and rehearsed, mainly because I could coordinate piano and bass lines and rhythms. While I missed the interaction with the live bass player, I thought we brought a different dimension to the group. Does anyone else typically play without a bass player (organists - no need to respond about your prehensile feet!)
