Tomorrow, check out the music and comedy of Reverend Billy C. Wirtz. His performance combines satirical, irreverent humor with blues- and gospel-inspired piano playing. No subject is taboo for this accomplished musicologist. Wirtz performs at 7:30 p.m. at Rams Head Tavern, 33 West St., Annapolis. Tickets are $20. Call 410-268-4545 or go to ramshead tavern.com.
