Donuts with the 'Brutalist Donut' at the Hirshhorn Museum: The Smithsonian's lone brutalist building has affectionately (or derisively) been referred to as a “brutalist doughnut.” The museum will celebrate its round, empty-in-the-middle design on World Architecture Day with free Sugar Shack doughnuts for all visitors, in addition to architecture-focused talks and tours. Highlights include Amanda Kolson Hurley, author of a Washington Post Magazine article on preserving — and improving — brutalist architecture, discussing her story at 12:30 p.m., and @brutalistdc founder Deane Madsen leading an Instagram tour of the building at 6:15 p.m. 10 a.m. to 7 p.m. Free.

All Things Go Fall Classic at Union Market: The Virgin Mobile FreeFest is no more. Sweetlife has shrunk dramatically. Trillectro is M.I.A. Landmark Festival was D.O.A. This festival-less landscape makes the annual All Things Go Fall Classic even more vital, so it’s promising that organizers have scaled up to a three-day event and traded last year’s sea of mud at Yards Park for the festival’s previous home at Union Market. Galantis, Young Thug and Foster the People top the 20-artist bill, but don’t miss the undercard acts, including Fletcher and Washington’s own Innanet James. Gates open at 4 p.m. Friday and at noon on Saturday and Sunday. $69-$250.

Rich Medina at the Kennedy Center: The collaborative concert featuring jazz pianist Jason Moran and hip-hop emcee Q-Tip of A Tribe Called Quest is long sold-out, but the after-party is open to all. Pioneering DJ Rich Medina brings his collection of hip-hop, funk and house to a dance party in the Kennedy Center's atrium, where he'll be joined by the Marksmen for a set honoring the beginnings of hip-hop. 9 p.m. Free. 

— Fritz Hahn, Carrie Donovan, Macy Freeman, Holley Simmons and Savannah Stephens
