The hour King played was not the type of music (straight blues) most of the younger fans had interest in or excepted when they bought tickets so I guess I get it that some didn't really enjoy that part of the show (the kids around me started comlpaining to one another about 20 minutes into the BB appearance). Being a little older and straight blues being what lights my soul on fire, I was beside myself. Blues is what made me pick up the guitar in the first place.
From a guitar players standpoint it's my opionon BB's blues vocabulary is second to none and this night was no exception. He says more with less notes then anyone in the game. Again, younger people who just wanted to see smoke come off Trey's guitar in typical Trey fashion may never understand how impressive BB's playing is or was that night.
What I remember most was watching Trey's face and body language. I got the feeling Trey was so selective with his notes, as if he needed to show BB that he too can speak the blues. Trey looked and played like he had been preparing for this moment his whole life and wanted to impress BB the way a boy might want to impress his father. I might actually say he seemed nervous.
There have been many shows for me since and hopefully will be many more in the future and most of those will be standard good night/bad night Phish shows. This was a one time thing and I thank God that it happened in front of me.
Without BB this was another night in life of Phish. A good time with some great moments but the show wasn't going to be blogged about for a decade after as epic. So in the end, the only reason this show gets noticed is that one hour of straight blues.
