Bob Weir sat in with Lukas Nelson & Promise of the Real last night. The Grateful Dead/Furthur guitarist joined Nelson for “Jailhouse Rock,” “Little Red Rooster,” “Maggie’s Farm” and “I Shall Be Released” at Mill Valley, CA’s Sweetwater. Weir helped reopen the club earlier this year and has joined a variety of artists at the venue over the course of the past few months. Earlier this year Weir and Nelson also collaborated at both Weir’s TRI Studios and San Francisco’s The Independent. Nelson will film a webcast at TRI Studios on April 17.
