Despite what you might have heard on a recent Saturday Night Live skit, Parker is still “not afraid of no ghosts.” But these days, the Ghostbusters pop songwriter is more of a smooth-jazz/blues artist, and the singer-guitarist is touring in support of the musically eclectic I’m Free. Monday, Oct. 26, at 8 p.m. and 10 p.m. Blues Alley, 1073 Wisconsin Ave. NW. Tickets are $35, plus $10 minimum purchase. Call 202-337-4141 or visit www.bluesalley.com.
