Last night at the Big Easy Concert House in Spokane, WA, Joan Baez sat in with RatDog for two songs. Baez had performed earlier in the evening at the nearby Met Theater and then arrived at the Concert House for the beginning of the second set. She contributed vocals to ‘K.C. Moan’ and ‘It’s All Over Now Baby Blue,’ with RatDog’s Bob Weir on acoustic guitar. Later that night, all of RatDog save Weir appeared on percussion during a jam that bridged ‘Ashes and Glass’ and ‘Standing on the Moon.’ RatDog performs at the Valley Ice Garden in Bozeman, MT this evening while Baez is at the Aladdin Theater in Portland, OR.
