This is what festivals like Mountain Jam are all about. Halfway through UM’s show, a surprise guest appears unannounced on the key. What appears to be Willy Wonka, promptly melts everyone’s faces on the keys solo of Pink Floyd’s Breathe. After his blistering sit in on the keys, he is revealed to be Marco Benevento.

For those Mountain Jam early birds, UM put on a hell of a show on Thursday night. Papa Warren made a guest appearance earlier in the set before this epic dub version of “Breathe.”

After seeing all the surprise guests at Mountain Jam, I was desperately hoping this one would surface. The fan-footage is a little shaky, but the sound is great. Enjoy musicians at the top of their game covering this classic Dark Side of the Moon tune.
