Artscape in Baltimore: Many festivals promise “something for everyone.” Baltimore’s annual Artscape — the country’s largest free arts festival — comes closest to delivering. The three-day gathering in the city’s Station North and Bolton Hill neighborhoods is a riot of originality. Wander through the installations and interactive works created by Baltimore artists and a marketplace with almost 150 vendors, and you’ll find a “Dance Camp” with performances by local pros and talent shows for amateurs; performances by the Baltimore Symphony Orchestra, experimental opera groups, indie rock and hip-hop acts; pop-up comedy and improv groups; fancifully decorated “art cars” and free movie screenings. The biggest draws are the evening concerts, with TLC (Friday) and Toots and the Maytals (Saturday). Friday and Saturday from 11 a.m. to 9 p.m.; Sunday 11 a.m. to 7 p.m. Free.

Janelle Monae at the Anthem: “Abandon your expectations about art, race, gender, culture and gravity” reads the sixth of Janelle Monae’s Ten Droid Commandments, a pamphlet the singer has distributed at her shows for years. The triumph of Monae’s most recent album, “Dirty Computer,” hinges on that very notion. Monae, who spent years shrouded in a sanitized sci-fi aesthetic, now allows herself a transparency that once seemed to elude her. This new universe is free of constraint, filled with vibrant songwriting and splashy melodies as bold as the colors that replaced the black and white trappings of the past. 8 p.m. Sold out.

20th anniversary at African-American Civil War Memorial and Museum: The African American Civil War Memorial celebrates two decades on U Street NW with two days of living history exhibits, reenactors and storytellers at museum, including a Friday performance of the play “Harriet Tubman: The Chosen One.” Authors of books on African American and Civil War history will discuss and sign their works both days. On Saturday morning, a walking tour (10 a.m. to noon) follows the new George Washington Williams Memorial Trail from Howard University to the memorial. Williams, a Civil War veteran and minister, attended Howard University before writing the two-part “History of the Negro Race in America.” Friday from 10 a.m. to 4 p.m. and Saturday from 10 a.m. to 5 p.m. Free.

Two Inch Astronaut at Black Cat: Local post-punk fans were saddened when Silver Spring-based band Two Inch Astronaut announced an “indefinite hiatus” earlier this year. The group, known for its catchy and quirky hooks, has embarked on a final tour that fittingly concludes in the Washington region. 9 p.m. $10.
