Watch Carlos Santana, Bob Weir in a Preview of Tonight's Jerry Garcia 70th Birthday Tribute Webcast

Ebet Roberts/RedfernsA preview of the webcast event marking Jerry Garcia's 70th birthday taking place tonight at Bob Weir's state-of-the-art TRI Studios in San Rafael, California, has been posted at RollingStone.com. "Move Me Brightly" will feature a variety of performances, a special video interview with Carlos Santana, the reading of a poem written in Jerry's honor by David Crosby and appearances by a number of the late Garcia's family members and friends.

In the teaser clip, Santana talks about the first time he met the Grateful Dead frontman, at the San Francisco park The Panhandle around 1967.

"I was taking a solo on this truck…and I closed my eyes, and when I opened them up, Jerry was right there and Michael Bloomfield," recalls Carlos. "They were smiling...like two Cheshire cat Buddhas. I guess they liked what they heard."

Santana adds that Garcia was "always very inspiring and encouraging to me."

The preview also includes footage of Weir talking about what Garcia might have felt about TRI Studios.

"I don't know if he'd consider it a waste of time and money," offers the Dead singer/guitarist. "I think he'd wig out in here, but I built it in his fond memory."

"Move Me Brightly" will be viewable at TRIStudios.com and at Yahoo! Music starting at 6:30 p.m. PT. Actor Luke Wilson will host the festivities.
