After years of promises, broken promises, site switch-ups, sweetheart lease deals, secret design competitions, more broken promises, and lots of compromises, The Broad art museum finally opens next week on Bunker Hill in a honeycombed building by Diller Scofido + Renfro, a boxy counterpoint to its undulating Disney Hall neighbor.

The press got a sneak peek yesterday, with the space decked out in its inaugural exhibition of contemporary art from the private collection of museum patrons Eli and Edythe Broad (Eli made his fortune building tract housing in the suburbs and he and his wife are now LA's foremost arts patrons, in a three-way tie with Wallis Annenberg and David Geffen, perhaps)—there are Jeff Koonses galore, and works by Roy Lichtenstein, Andy Warhol, Ed Ruscha, Kara Walker, Barbara Kruger, John Baldessari, Jasper Johns, etc. etc. etc. There's also Yayoi Kusama's "Infinity Mirrored Room — The Souls of Millions of Light Years Away," a disorienting mirrored room full of LED lights that's only open to one viewer at a time.

The show and the museum officially open September 20 and admission will be free in perpetuity—there are, as a promise, no admission desks in the Flinstone-y lobby, just smartphone-wielding museum workers to check you in before you ascend the long escalator (or tube elevator) to the main galleries on the third floor. You can then make your way down through the peekaboo storage area on the second floor to more first-floor galleries. Reservations to visit can be made online.
