I wonder if a band could put together a live stream concert published to a private stream sent to a movie theater. A bunch of fans of the band could get together and have the concert experience with fellow fans but not have to pay as much as an in-person concert. Movie theaters would have another way to get people in the door.
There was a push in the cinema industry a few years back to get more into live events, concerts and stuff like that, but seems like it didn't really take off like they wanted.
This definitely happens. Last time Dead & Company came to town, it was simulcast in the local movie theater. Tickets to the show were only available on a raffle basis since the venue didn't hold nearly enough people.
Then again, the Dead were also pioneers of permitting and encouraging the bootleg scene.
