The British guitarist Adrian Legg is famous, sure—after all, he’s shared the stage with Joe Satriani, Eric Johnson and Steve Vai on their huge G3 tour. But versatility may be his biggest asset, both in music and in travel. This week, he plays the showroom at the Crystal Bay Casino in Lake Tahoe just before heading up to Shingle Springs, Calif. (where?) and then dropping in on Marin. It’s a good guess that he’s in town to check out the Bay Area World Guitar Show at the Marin Center (Saturday–Sunday, Jan. 8–9; 10 Avenue of the Flags, San Rafael; 10am; $15), a huge convention of dealers, players, luthiers and collectors. He’ll pick up a tour date while he’s at it, dazzling a crowd with his incredible fingerstyle playing on Saturday, Jan. 8, at 142 Throckmorton Theater. 142 Throckmorton, Mill Valley. 8pm. $18–$21. 415.383.9600.
