Grateful Dead guitarist Bob Weir has teamed up with members of the National – Aaron Dessner, Scott and Bryan Devendorf – for a collaborative night of music and voter education. On Saturday, the musicians will congregate at Weir's TRI Studios in San Rafael, California for the Bridge Session, a live webcast featuring two musical sets and a political discussion. The performances will include selections from both band's catalogs, as well as some politically-minded cover songs.
