This summer will bring the second edition of In It Together Fest and the fourth annual Trillectro, two music festivals that take aim at the D.C. region’s seemingly inexhaustible supply of 20-somethings.

In It Together Fest — the punk-skewing festival that plans to take over mostly DIY venues from July 30 to Aug. 2 — announced the latest updates to its already beefy schedule last week, including performances from locals Paint Branch, Teen Mom, Shark Week and Mattress Financial. In It Together Fest hosts its main showcase at Columbia Heights church St. Stephen’s on Aug. 1, featuring Philadelphia’s Cayetana and Baton Rouge heavies Thou.

Organizers of trendy hip-hop and electronic event Trillectro, meanwhile, dropped their own news today: a date for the 2015 concert. Trillectro will take place Aug. 29 this year, according to the fest’s social-media accounts. No word on what venue or acts can be expected. (Co-organizer Modi Oyewole says venue information is coming this week.)

By this time last year, Trillectro had already announced its schedule for the 2014 event, which took place on RFK Stadium’s festival grounds.

More updates are forthcoming from In It Together Fest, which is also planning a 30th anniversary celebration for punk-rock activist group Positive Force, scheduled for Aug. 2 at St. Stephen’s.

“We have a surplus of bands and we’re running out of space,” says Mike O’Brien, an In It Together Fest co-planner who operates his printing business out of Hole In The Sky. Bands’ overwhelming interest in the event—which runs July 31 to Aug. 3 at numerous local venues—stands as a testament to the months of work O’Brien and his fellow organizers have put into what may be D.C.’s first sweeping, multivenue DIY festival.

But while the folks from Hole In The Sky and fellow DIY space The Dougout have handled many of the event’s logistics, much of the heavy lifting—like booking the shows—has been the work of the larger community. O’Brien says the idea was to bring together the city’s diverse and sometimes disparate arts spaces under the banner of a major DIY festival—so participating venues were given dates to work with and told to book the shows they wanted to see.

The result is an eclectic mix: a mishmash of straight-ahead punk rock, spacey fuzz pop, singer-songwriter crooning and various styles in between.

“That is a product of the structure of the fest that we set out from the start to make sure happened,” O’Brien says. He told the venues, “Do whatever you want. We’ll support you in promotion and make sure people know about [the shows].”

Getting the word out clearly has not been a problem. At the moment, roughly 10 bands are waiting to see if they can land a spot in the fest. O’Brien says he and the other organizers are kicking around ideas to fit them all in, including adding new venues—like record stores—and shoehorning them into the already beefy lineup.

Organizers have posted the festival’s most up-to-date schedule on the In It Together Fest website (see the flyer below). So far it includes 17 events at 16 venues—and it’s not all music: There’s an Alley Cat bike race, a drone brunch, a skate showcase, and a centerpiece event Aug. 2 at St. Stephen’s Church. But as O’Brien says, more happenings could be tacked on in the coming days. The heavy lifting might not be finished yet.
