Allman Brothers Band, Gov't Mule, and The Dead guitarist Warren Haynes resumes his Jerry Garcia Symphonic Celebration concerts tonight (July 30th) at Morrison, Colorado's Red Rocks Amphitheatre. Joining Haynes and his band for a night of classic Grateful Dead music will be the Colorado Symphony. August 1st marks what would've been Garcia's 71st birthday.

With several cities already under his belt, Haynes says he's looking forward to stretching out during the remaining Garcia symphonic shows: "The ones that are left are Red Rocks, L.A., and San Francisco. It was really amazin.' I had never worked with a symphony before and was a nervous wreck about the whole thing until we actually started doing it, and then it started to feel great. And I knew it would. I just knew I had to get passed the initial anxiety. I called Phil Lesh and got his advice on picking some arrangers and it just kind of happened organically, which is how I love for things to happen. It's been a blast. I'm havin' a great time doin' it."

Tomorrow night (July 31st) Haynes will team up with Grateful Dead co-founder Bob Weir for a webcast at Weir's TRI Studios. TRI (Tamalpais Research Institute) is Weir's "state of the art, world-class video streaming venue and recording facility." Fans can log on to the webcast at 7:00 PM CST at http://www.tristudios.com/events/take-me-2-tri.
