So I got a call to rehearse and maybe play some gigs with a big band. Anythink in particular I should know from you guys? The largest band I've played with to date is 5 pieces, more of a rock/groove thing. The bandleader wouldn't really give me any hints on the tunes we'd be playing other than to say 'anything from swing, 1/2 time, double time, to samba' - what would you guys do to prepare? I've always been in more calculated environments, so knowing it will be sink or swim is a bit nervewracking, although I am sure I will do fine.
