Hmmm...I've listened to the first track and plan to listen to more tracks. I can't say it's a great recording but perhaps better than a lot of other recordings of that genre. On that first track, the audience mostly collapses to the left and right M100s. A couple of times I heard the audience behind the M100s and to the inside. On the M5, the audience is behind the speakers and pushed "back". The M100s reveal more detail.
