a rothbury observation
The vast majority of people who were at The Dead, and I presume String Cheese Incident (I don't know because I didn't see that show), are not fans of music. Or at the very least, they weren't there for the music. That's not to say that there aren't fans of The Dead (and the like) who are absolutely all about the music, but only that they were very under represented at the show.
Steph and I saw 27 bands at Rothbury this year, and the contrast between most of the shows and the "jam band" shows was stark. It was all in the facing. At most shows, people were actually facing the stage, or in that general direction, obviously focused on the music, usually dancing. There was some dancing at The Dead, but mostly people were walking around talking, smoking weed and yelling "WHERE'S THE PARTY?!"
They were there for the party, not for the music. Maybe like 80% party and 20% music. It reminded me more of a tailgate party than a concert. I'm not sure why this surprised me, but it did. I felt a little sorry for some of the acts there who were performing for much smaller crowds than they probably should have with 40k people in attendance, because everyone wanted to be where the party was. Where everyone else was. Probably better that way, now that I think about it. I'd rather be with a smaller group of enthusiastic music fans than a giant mob of loud, drunk assholes. I hope The Dead come back every year, like a giant annual black hole, sucking all the douchebags away from the better stages.
