There really haven't been much. And the last big one was Duran Duran and it really was the only big one in a LONG while.
I do think that they can be considered additional concert venues for when there is no show playing. I mean most of the time there is something like there was with Duran Duran it is usually these musical acts who try to make thier gigs a spectial from the get go.
But, I mean you can easilly put a rock band in a thetre that is dark. Sure you wouldn't be charging typical broadway prices. But, from the owners standpoint they will be makinging something when the theatre isn't housing a show.
