Stolen idea from the GD sports venue thread...
First- Concord Pavillion, The Tubes with Joan Jett opening
Last- Oakland Metro Operahouse, Allegaeon
Best- Tough to answer....from a pure experience standpoint, it'd go with the August Hall. Clean af, great acoustics, and still very intimate. But emotionally I'm really connected to the Oakland Operahouse, it's dingy, dirty, bathrooms fucking stink, and I have yet to not be in the front row for a string of insane shows there (Allegaeon, Orphaned Land 2x, Anathema, Firewind, Alestorm, Gloryhammer, Intervals, Mindmaze and more)
Worst- Shoreline Amphitheater, Huge sprawled out venue built on a former dump so it always has a stinky edge to it. Hate that place even though I've seen some pretty sweet shows there (Sabbath, Grateful Dead, Yes_)
