Rock god Lindsey Buckingham, touring behind his self-released Seeds We Sow disc, plays Goucher tonight. The disc showcases Buckingham's nimble and expressive guitar playing and bittersweet vocals to full effect, and, in all honesty, the Fleetwood Mac frontman has rarely sounded better. At 6:30, a cappella group Cadenza plays a benefit dinner at the Shot Tower to help raise money for the Tower's restoration. Reservations are required. And Madeleine Peyroux and Nellie McKay, an intriguing double bill, play Strathmore. Tomorrow, Lafayette Gilchrist plays Windup Space, graffiti legend Frank Arthur signs prints at Tag Galleries in Fells Point (during the Fells Point Fun Festival), and Shodekeh and Audrey Chen play the BMA's "after hours" event that closes the Baker Artist Awards exhibition.
