I too have spent a many nites or days depending on the gig grining baring it..waiting for the drummer and base player to find there mutual pocket, a lot of times it never happens and makes a 45 minute set seem like 2 weeks and you have 4 more sets to go...time for a beer or two. On the other hand, it is bliss to sit in with players who from hit time to closing everyone is in the pocket and you dont want to stop playing..With that said..I/we players that are not having fun talk or at least try to talk to the drummer and or base player to give ideas..sutle hints..etc. Sometimes it helps them along..sometimes not..worth the try tho.
