The Future of Ensembles?

My dean directed my attention to this phenomenon yesterday:

I'm sure that the ensemble does more than play drones and theme songs from Zelda, but I haven't found any full length videos of performances other than this one at Michigan last month. I think harnessing new musical instruments is a great idea (and can you imagine how they would sound using Bloom:)

So what do you think? The future of musical ensembles? Or catchy gimmick?
