+1 on the suit thing.Ok. But Dave Brubeck was a small jazz quartet, you know
I think if you wear a 1950s style suit that would make you look more jazzy than the kit would.
The drums you can play and any of them will sound like drums (and no one will notice anything except the colour).
But the suit will definitely impress everyone and class up the joint !
You'll be on that leader's speed dial list before you even start to set up.
