1) Set on what would tragically be the final afternoon of Dr. Martin Luther King’s life, Katori Hall’s Olivier Award-winning play The Mountaintop features just two characters: Dr. King and Camae, a young African-American maid working at the now-infamous Lorraine Motel in Memphis. That’s all the play contains: dialogue between two people in a hotel room, but within that is a wide span of commentary about struggle, race relations, and uncertainty as King considers his legacy and Camae, one of the benefactors of his life’s work, contemplates some of the same issues. With Albert Jones and Bianca LaVerne Jones filling the two roles, City Theatre is putting on the play for a four-week run that starts today. 5:30 p.m. 1300 Bingham St., South Side.
2) A mainstay in the Lawrenceville art community, Atticus Adams trims and arranges wire mesh and other industrial materials into weird, wiggly shapes. His work can resemble everything from pollen to sea creatures to microscopic life forms, depending on your imagination. (We’re particularly fond of his giant squid-resembling big red pieces.) He currently has a show at BE Galleries, and these gorgeous assemblages of weirdness and form will hang there, intriguing and mildly freaking passersby on Butler Street, until Feb. 15. 11 a.m. to 6 p.m. 3583 Butler St., Lawrenceville
3) One of Pittsburgh’s hardest-working bands, the Harlan Twins seem to play a gig as often as we hit a pothole in the road this winter. Between shows, the five members of the neo-folk-rock quintet somehow find the time to produce music that’s top-notch, in terms of both songwriting and production quality. Plus, the bi-gender lead vocals of James Hart and Carrie Battle create a great dynamic. Tonight the Twins headline Mr. Smalls, with support from The Red Western, Triggers, Molly Alphabet and Paul Luc. 7 p.m. 400 Lincoln Ave., Millvale.
4) Sundog 6 is a cover-playing party band, but instead of the usual mix of Motown and classic rock, their distinctly modern repertoire includes songs by Of Monsters and Men, Florence and the Machine, and Edward Sharpe and the Magnetic Zeroes. They bring it to the Hard Rock Café tonight. 10:30 p.m. 230 W Station Square Dr., Station Square.
