I just got back from seeing "Cracker Acoustic" tonight. Not the whole band, just David Lowery and Johnny Hickman.
'Twasn't really acoustic, but it gave me some ideas of how to convey rock in a plugged-in acoustic format.
From my days doing a 'rocking acoustic duo' I had figured out the whole 'chord with your left, hit as many bass notes as possible, strum with the drum pattern' thing.
David had gone a step further. He was playing a cheap-o nylon string with a piezo, while Johnny was playing his Les Paul. I was a little confused at first.
However, David's choice of guitar worked perfectly. When appropriate, he could thump the top as a bass drum, and a rake across muted strings made a perfect piccolo snare sound. He was an entire band in his right hand.
Food for thought, anyway.
