Hey, I'm a bassist in a funk/jazz/rock band and we feel like we've got a lot of potential, however our vocalist/keyboardist is extremely busy and can never perform. So the guitarist, drummer and I have been playing with the idea of doing some sort of Medeski Martin & Wood style jam band gigs as a trio. We would have a set of chord progressions or riffs or ideas that we would improvise off of on stage. Does anyone have any experience with playing in a jam band like this? I am just trying to gather as much info as possible in regards to what makes a good jam band, what level of preparation or rehearsal is actually required if most of what I'm playing is just improvised, etc. ye four of us jam every day for at least an hour, so we feel each other already when we play. Thanks!
