Start spring break early with themed happy hours and live music from a Baltic alternative rock band and Canadian singer. There’s also a comedy show with a local lineup and a discussion with author Michio Kaku as part of Sixth & I Synagogue’s Genius Festival.

Monday

Reading Room Comedy Show: Chris Brandt will host D.C. comedians for a second night of comedy in the ornate, library-like Reading Room adjacent to a bar. Petworth Citizen’s website states that even if the comedy isn’t up to par, there’s a breadth of Tom Clancy novels to leaf through.
Petworth Citizen, 829 Upshur St. NW. 7:30 p.m. Free.

“Mappy Hour” Drink Specials: It may still be too chilly to sip drinks outside, but the folks at Outdoor Fest are inviting nature enthusiasts to a happy hour for the second time. Last year, about 120 people showed up to discuss the great outdoors – and drink. Attendees should bring a map.
Meridian Pint, 3400 11th St. NW. 7 p.m.

Tuesday

Ewert and Two Dragons Concert: These musicians hail from Estonia, where they’ve gained recognition since their 2011 hit “Good Man Down.” Their twangy alt-rock sound is nothing unusual, but this is a much cheaper way to get your mellow, European foursome fix.
DC9, 1940 9th St. NW. Doors at 7:30 p.m. $10.

Michio Kaku Talk: Catch the author of “Future of the Mind,” in which he writes about the research that goes into the study of the human brain. One day, Kaku has said, people will be able to take a pill to enhance their cognition and the contents of one’s brain could be uploaded to computers neuron by neuron.
Sixth & I Synagogue, 600 I St. NW. 7 p.m. $17.

Wednesday

Purim Party Draft Takeover: This Irish-Jewish establishment considers Purim to be the “Jewish St. Patrick’s Day,” and to celebrate the first evening of the holiday, Star and Shamrock will have drink specials and live music by local klezmer band Klezcentricity.
Star and Shamrock Tavern & Deli, 1341 H St. NW. 6 p.m.

PartyNextDoor Concert: Jahron Anthony Brathwaite, or PartyNextDoor, is an electric music artist with an R&B twist. He’s signed to Drake’s label and is best known for his four-track EP, “PNDCOLOURS.”
9:30 Club, 815 V St. NW. 10 p.m. $30.

Thursday

Desert Noises Concert: This indie band has come a long way since its underproduced “Oak Tree” in 2011. More recent releases, like “I Won’t See You,” are a more sophisticated take on sweet lyrics with catchy melodies.
DC9, 1940 9th St. NW. Doors open at 8:30 p.m. $10.

French Horn Rebellion Concert: When David Perlick-Molinari quit the Chicago Civic Orchestra in 2007, he asked his brother, Robert, to join him on a quest to blend dance music with traditional instruments, like the French horn. Their project became French Horn Rebellion, and the brothers refer to themselves as “band geeks gone wild.”
U Street Music Hall, 1115 St. NW. 7 p.m. $15.
