Angra150......I live here in SoCal and have been to both venues many times......The Avalon is pretty much standing room only and is right in the heart of Hollywood. The Galaxy is about 45 minutes south in Orange County.......I've been there many many times and its also a great venue - the crowd tends to be a bit tamer in OC and you don't get that LA vibe......I'll be at both!! I know I've been vague, but I prefer the Hollywood vibe, but the Galaxy is the better venue.......
