We have a nice list of jazz jams in Boston area, but what about blues/R&B/rock flavored jams? I'll start (just off the top of my head):
Sundays - Chris Brown at Tommy Doyles (not sure what "pro jam" means. It could be invitation only? Or you just can't suck?), Stones Public House, Ashland(formerly John Stone Inn),
Mondays - Spontaneaous Combustion at Beehive, Boston (jazzy but not too much), Smokin' Joe's BBQ, Brighton.Wednesday - The tavern in Plainville
Thursday - The Next Page in East Weymouth, Acton Jazz Cafe has a strong crowd and relaxed scene.
