Thanks, Donny...
I used to play in a trio a few years back. Me, a singer/guitarist that sounded JUST like Jerry Garcia, and a scrub-board player! We called ourselves the Laundromatics
Some songs we used an old Atari to run Cubase, and sequenced drums (I have a Hart Dynamics kit, so we hired in local drummers to play with us live in the studio, and recorded the kit!) and bass, then played with it, but most of it we simply had the scrub-board player do his thing and I would play LH bass and kbds just live. We did a LOT of Grateful Dead, and that sequence (just bass and drums) is a relic from back then...
Happy days...
