Authenticity in Music Ensembles

I'd been mulling over a post dealing with what it means for an ensemble (and its music) to be honest and/or authentic. I know it's based on trust. You can't make meaningful music without trust. But beyond that I hadn't written it because I just didn't have my mind fully wrapped around the entire concept.

And then I saw this video. What else is there to say? It's all right here: Trust, Honesty, Authenticity.
