Here are a few more that have some pretty broad sound-stage - both are live recordings:
The link above is actually to an HD video mated to the binaural audio that I recorded. It's Indian-fusion music, and comes from a series of videos that were posted (all shot by Michigan Music Monthly) of the band Sumkali. It's interesting to listen to this versus listening and watching. I think there are seven or so excerpts from the concert, and all feature binaural audio.
Also, here's a link to an ensemble show that I recorded a while back. This was done in a small theater (seats about 90) with the mannequin head placed at stage center, facing the musicians. All of the performers were seated in an arc in front of the mannequin - maybe 12 feet or so away (approx 3.5 m). If I had to guess, I would say the total arc length was about 25 feet. As the set progresses, you will hear performers appear at hard left or right, but you will also hear the performers seated closer to the centerline; also, listen for harmony parts being sung by others either close to the performer, or on the opposite side of the stage.
The first set features originals whereas the second set features covers of Joni Mitchell tunes.
Lastly, listen for the rains during part of the performance - pretty cool in the headphones:
