Have you heard of the VEVO GO SHOWs? They are "on the fly" performances, where a current artist/group grace somewhat-unsuspecting fans with their presence. When I need a pick-me-up, I start at the top and roll through. It all reminds me that any kind of creative endeavor, while beautiful when polished, is also marvelous in the raw.
Enjoy this clip from my favorite GO SHOW!
