After several delays, the new Broad Museum, built by philanthropists Eli and Edythe Broad, is scheduled to open Sept. 20, and there’s still a chance to be among the first to visit it, LAist reports. Free tickets for the contemporary art museum downtown, next door to Disney Concert Hall, can be reserved online, beginning Monday. The museum will feature more than 250 works from such artists as Andy Warhol, Barbara Kruger and Kara Walker.
