Critic’s picks: Pop music

JAMES MCCARTNEY Yes, that McCartney. But if you look past the surname, the young singer-songwriter has plenty to offer on his own with a familiar but solid brand of winsome pop. The early show is sold out but the late show still has seats. May 20, 9:30 p.m. Club Passim. Tickets: $15. 617-492-7679, www.clubpassim.org

PITBULL & KE$HA This headscratcher of a double bill sounds like a sitcom waiting to happen. Expect Pitbull to bark out dancefloor dominators like “Don’t Stop the Party” and “I Know You Want Me (Calle Ocho)” and Ke$ha (inset) to pour on the glittery party girl pop of tunes like “TiK ToK” and “Die Young.” May 23, 7:30 p.m. Comcast Center. Tickets: $40-$155. 800-745-3000, www.livenation.com
