I'm going to go out on a limb and give my opinion of The 2013 Furthur:
I think the Band has tightened-up nicely and is playing at Grateful Dead Level (GDL)
I believe the use of set-list has been a tremendous help. The vocal harmonies are sweet and "In-Key". They compliment the other instruments.
Ever since the "Sweetwater" shows I was very impressed with the solid quality of JK's leads and slide guitar.
Jeff too. I just dig his mastery of the piano and style on the Hammond B 3 organ. I love that distinct sound from those Leslie speaker cabinets (Brent stacked 2 behind Phil and 2 around him n Jerry).;
This years pay-per-view gigs: Sweetwater's, Ramble's and Locken' Fest where most welcomed and much appreciated. I could for the first time see the band playing live. Let me explain...I've been too several Furthur shows but usually only catch a head or what ever was being projected. I am also a transplant survivor who doesn't handle long periods of waits in the outdoor sun or risk exposure to flu and tour-hack stuff that goes around. (Avoid Mosh Area) But for me and other patients in hospital, your pay-per-view's were a hit with Locken being a home run.
Good luck with all of your 2014 projects.
