Support the artists by buying their official records and attending their shows.
I'm almost positive this isn't soundboard. You can hear people talking during the recording (One person mentions not being able to get good photos of the band). That said, it's a pretty good audience recording, so you should still pick it up if interested.
Also, the audio is 256, not 320. Probably doesn't make much of a difference, but I thought I'd mention it to anyone that cares.
