I stepped back from being out front to playing bass. So we started switching: I'd play bass on one song, we'd switch on the next song; I'd play piano... we'd play mandolin.
I play a percussion instrument, not a musical saw; it needs no amplification. Where it's needed, they put a microphone in front of the bass drum. But, I don't think it's necessary to play that way every night.
When I started playing the bass, I became kind of fascinated by it and started investigating various styles of bass playing, and I was really struck with funk music, mainly American funk music - Stanley Clarke, Funkadelic and that kind of stuff. That comes out in a couple of songs like 'Barbarism Begins at Home.'
