someone posted that here not too long ago, I've seen it quite a few times and just watched it in its entirety a few days ago, it's very clever, someone got right in there and did the sounds right along the actions you see happening. Funniest comment attached to the vid I saw that's been cracking me up all weekend was how awful Phish jams are and how he/she would have to take a major bong hit just to get through it.
I'm a fan of Phish and the Grateful Dead myself, but after fifty shows (Ph) I definitely have points where I'm feeling a show drag(specifically for me: song choice, I'm a song-chaser). Makes it a hundred times more fun when you start learning to play the songs yourself, and really the Dead and Phish catalogs are gigantic and lush. Everything in life's going to have its blah moments, I certainly wouldn't want everything to be super exciting and 'perfect' all the time, and expecting that will make anyone fall flat.
