The Guitar Blues Tour opens the first of 31 dates tonight in Pittsfield, MA. The Colonial Theater will host this evening’s show, which will feature Jorma Kaukonen, Ruthie Foster and Robben Ford. At each of the stops on the tour, Kaukonen, Foster and Ford will perform a set of their own music. Then the three guitarists will deliver a final set in which they will perform together. The Guitar Blues Tour will cross the country, wrapping up on March 8 at The Triple Door in Seattle, WA.
