The DJs, bands, dance nights and parties you need to plan for in the next seven days. We'll post more ideas throughout the week.

Monday was Ernest Hemingway's 115th birthday, but cocktails will be lifted in Papa's honor Tuesday evening at Mockingbird Hill. Local author Philip Greene, who wrote the Hemingway literary cocktail guide "To Have and Have Another," will speak about Hemingway's favorite drinks and sign copies of his book, while resident bartender and sherry expert Chantal Tseng creates cocktails using Sherry, which Hemingway fell in love with during the Spanish Civil War, and Papa's Pilar Rum. Doors open at 5 p.m., and drink specials will be offered until 7.

Meridian Pint is a strange place to celebrate Belgian Independence Day, since the Columbia Heights beer bar only sells American beer. But for this occasion, Ommegang and Boulevard -- both owned by Belgian powerhouse Duvel -- are taking over 12 of the Pint's 24 taps, filling them with Belgian-style ales. The draw might be the debut of Ommegang's Belgian Independence Day IPA, but there will also be the 2013 and 2014 vintages of Boulevard's funky Saison Brett, a 2012 Ommegang Independence Day Tripel, and the Ommegang/Chouffe collaboration Gnomegang. Doors open at 5 p.m.

Brooklyn duo denitia and sene comes out of the genre-averse stew of R&B, downtempo and electro-pop that some describe as chillwave. With influences ranging from Sade to the Beatles, their sound is a combination of dreamy female vocals over seductive digital backdrops. The increasingly hot pair brings its intimate space-soul sound to Liv.

Athens, Ga.,'s Terrapin Beer Co. continues to show up on an increasing number of tap and can lists around town. As good as Hopsicutioner and RecreationAle are, you're doing yourself a disservice if you haven't tried the brewery's more interesting and experimental side. Brewmaster and co-founder Spike Buckowski is making the trip up to D.C. this week, bringing 14 Terrapin drafts and five casks to ChurchKey. Included are the brewery's two most recent small-batch "Side Projects," Guano Loco and Moonray; barrel-aged versions of Monk's Revenge and Wake and Bake imperial coffee oatmeal stout; and a number of other rarities. (ChurchKey has the full list.) Buckowski will be on hand to talk about the beers, beginning at 6 p.m.

By the end of July, we don’t usually need a reason to hang out on rooftop decks with tropical drinks, but Shaw Main Streets is offering a good one. The Rooftop Hawaiian Luau Bar Crawl on Saturday afternoon starts at DC9 at 1 p.m. before heading off to 1905 (2 p.m.), Dunya (3 p.m.), the Brixton (4 p.m.) and Nellie's (5 p.m.). Happy hour drinks, food specials and raffles will be offered at each stop, and there will be prizes for the most festive outfits, so Hawaiian shirts and grass skirts are encouraged. Tickets are $15 in advance and $25 at the door, and allow access to discounts at each bar.

Speaking of day parties, it's time for another edition of the Rock Creek Social Club's Grilled Cheese Social on Marvin's rooftop deck. A full menu of sandwiches goes beyond what mom used to make: The Green Machine, with spinach, pesto and melty gouda is $9, as is the Kick, which adds bacon and sliced jalapenos to a base of cheddar and gouda. Toss in $4 rail drinks, $5 beers and the sultry summer sounds of the Rock Creek DJs and you've got some perfect cookout vibes. There's no cover charge, and the party runs from 1 to 8 p.m.

"Purple Rain" isn't the greatest musical of all time, but the stunning soundtrack and concert sequences, including "Let's Go Crazy" and the title track, have sealed the film's place in music history. This weekend is the 30th anniversary of the film's release, and DJ Dredd is celebrating by taking over the Black Cat mainstage. "Purple Rain" will play on a projection screen at 9 p.m., followed by an all-Prince dance party of hits, rarities and remixes. Wear your favorite purple outfit for the occasion: The best "Purple Rain"-inspired costumes win cash prizes. Tickets are $10 in advance and $12 at the door.
