Got a gig tonight playing with a trombone and a piano player, and no drummer. I took the job because I very much need to learn how to get a great time feel playing without a drummer; it would do wonders for my playing. However I'd like to make this learning stage go as quickly as possible so that these guys will call me back. Especially upsetting is the fact that we are playing more than a handful of latin/bossa/samba tunes, which really highlight how poorly I play. Going back to swing after playing one of these tunes, I feel like Ray Brown! Do you guys have any recommendations of things I can practice to help me out with this, or ideas for keeping the groove on the bandstand? Thanks a lot.
