Grateful Dead's Bob Weir Jams With Members of The National (Video)

"The Bridge Session," a live webcast and political discussion produced by HeadCount, was beamed from Weir's San Rafael studio and featured acoustic performances of songs from both bands' catalogs.

The Grateful Dead's Bob Weir teamed up with The National's Aaron Dessner and brothers Scott and Bryan Devendorf on Saturday night (March 24) for a live webcast. Beamed from Weir's TRI Studios in San Rafael, the two-set event, called California for the Bridge Session, included music from the Dead catalog and a few songs by The National. A select small audience was invited to see the performance which also included political discussion.

The event was produced by HeadCount, a non-paritsan group that uses live music events as a way to promote voter registration (Weir is on their board). Political panelists who contributed to the conversation included indie presidential candidate Buddy Roemer, media advisor Mark McKinnon (who's worked with former President Bush, Sen. John McCain, Bono and Lance Armstrong) and activist Jessy Tolkan.

As for the music, Weir says he likes The National's songs so much, he might include them in an upcoming solo acoustic tour. And we wouldn't be surprised if some Dead tunes turned up in The National set list, too -- although not for a while since the Brooklyn-based band is in the midst of writing and recording their much anticipated sixth album. Their last release, High Violet, came out in 2010.
