Yeah, SS - that's what I'm talkin' about. You have a band up there, say Ramblin' Rose from 1-3. Then from 3-5, Ramblin' Rose has SEVERAL guests SIT IN with them (not subs) that don't have bands...like 2 guys on guitar come up for 3-4 songs, then they split and 2-3 other folks come up to join in for the next 3-4 songs, etc. Every band gets 2 hr slot just for them, then a 2 hr slot with several guests.
Hard to say exactly, until you see how many bands / how many solo performers we'd get.
But yeah, that's the ticket!!
ALSO, have time allotted for JAM SESSIONS (late, late night??) where 2 cats from one band, one cat from another, another from another...etc...
Then cap off the whole thing with some big sick-ass thing with a TON of people onstage as the final song.
