Everything else about it was a multi-sensory experience that I think would be totally flat in even the most advanced VR systems: the electric buzz running through the crowd at the opening notes to their biggest hit songs, the mass of people pressing together to get close to the stage, jumping up and down together to the beat, hundreds of others around you screaming along to the lyrics of their favorite songs, people crowd surfing, friends bringing over one too many rounds of beers, the band interacting with the crowd as a whole, feeding off the energy of the room...
Overall I'm not even a huge fan of live music, but it's hard for me to imagine a VR experience that captures all of the energy and human revelry of a great concert.
