I have to disagree with the central premise of this thread, and kindly suggest that some bands should not play some venues. I saw My Morning Jacket this summer at a small outdoor theater in Dillon CO. The sound was impressive beyond belief. I do station myself as close to the mix board as possible, and in this case was directly to the right of it. I also saw Spiritualized recently at a small indoor venue in Chicago and the sound there again was very good. GA show, make sure you're not under any overhangs or balconies for an indoor show and you're in good shape.
If we are talking repurposed basketball arenas with assigned seats then yeah, not going to be the best experience. This technology though is worth keeping an eye on....I thought U2 dabbled in it prior.
Last thing I'll add is some people want the live experience to sound exactly like the record. F that.....to me the live experience is about how well the band adapts, evolves and presents that song in this new venue outside the studio....that's the true test.
