I agree with adam; Jimmy Herring plays what I consider to be "on top" of the music, not really in it. Larry Campbell used to have that problem, but I think he finally "got" it. Barry Sless is my all-time favorite Phil & Friends guitarist; very tasteful and a consummate understanding of the music; a contributor who's ego is not in the mix. Least favorite would be Warren Haynes, who I consider to be a boring guitarist, and I've seen him more than perhaps any single guitarist, in incarnations including the Allman Brothers, Gov't Mule (a mixture of Grand Funk Railroad and Black Sabbath without the novelty or freshness), Phil & Friends, the Dead, and solo. Well, and then there's Chris Robinson, who is not a guitarist at all, in my opinion. The only band I have seen more than the Grateful Dead is Phil & friends, who I will also see tonight and Saturday. I never saw them with Derek Trucks, but I have heard those shows, and he is great. Jackie Greene is also surprisingly good.
I also agree with DenverEd; the price is high. I think Phil is attempting a west coast replication of Levon Helm's Barn in Woodstock. A friend of mine who plays there occasionally informs me that Levon gets $200 for a Saturday night Barn Dance performance. A good way to get revenue without the burden of the road.
I saw all the Phil & Friend Chicago shows, so was at the riviera in '07. Funny story, I was close to the stage on Phil's side, and the guy in front of me was dancing and runni ng into me repeatedly. I politely asked him to be aware several times, and he informed me that I just didn't "get it", that dancing was part of it (young kid). He kept encroaching on my space, so I grabbed his pants and pulled them down. He stopped being inconsiderate immediately. Maybe one day I will get it; we'll have to see!
Gone are the days we stopped to decide where we should go, we just ride...
