None of the bands I'm into are incredibly popular, so I haven't been to any of the massive outdoor expensive shows.
Really any Streetlight Manifesto show would be my favorite, they're shows have so much energy, and it's just a barrage of music, like they don't stop or stall or anything (besides a few quick water breaks between songs every now and then).
(not my recording and not the best sound quality, but it'll do the job)
