(NORTH ADAMS, Mass.) – The 15^th annual Bang on a Can Summer Music Festival at MASS MoCA concludes this Saturday, July 30, as always, with a six-hour Bang on a Can Summer Marathon concert from 4 to 10pm, in the Hunter Center, featuring works by special guest composer John Luther Adams, Steve Reich, George Crumb, Louis Andriessen, and Bang cofounders (and Pulitzer Prize winners) Julia Wolfe and David Lang.

Marathon attendees are encouraged to come and go as they please – to visit the museum’s café and shop, to take a walk, and to re-enter the concert at any time. Concertgoers are not expected to arrive right at 4pm nor to remain until the end. The marathon – based on the annual 10-hour event in New York City – is a relatively casual and freewheeling event, mirroring to some extent the renegade spirit of the music itself.

Among the works that will be performed by members of the Bang on a Can All-Stars, faculty members from the Bang on a Can Summer Institute, and festival fellows, are John Luther Adams’s “In a Treeless Place,” “Only Snow,” and “The Light Within”; Steve Reich’s rarely performed early work, “Music For Mallet Instruments, Voices and Organ”; Julia Wolfe’s raucous “Tell Me Everything”; David Lang’s “ark luggage”; Frederic Rzewski’s “Coming Together”; Louis Andriessen’s minimalist classic “Hoketus”; and “Boil,” a world premiere by Bang on a Can All-Stars clarinetist and conductor Ken Thomson.
