As the centerpiece of the 25th annual Bang on a Can Marathon, the looping resonances of Alvin Lucier’s 1969 minimalist masterpiece “I Am Sitting in a Room” should draw attention to the unorthodox nature of the World Financial Center’s Winter Garden as performance space. As it is, you’ll have 12 hours in which to contemplate this looming atrium’s palm trees, food court, and inside-outside vibe while reveling in Pauline Oliveros’s Deep Listening Band, Evan Ziporyn’s expanded arrangements of Conlon Nancarrow’s “Piano Studies,” Lois V. Vierk’s “Go Guitars,” Thurston Moore’s “Stroking Piece #1,” DJ Envee’s “Bang on a Can Remix,” the Grand Band playing Steve Reich’s “Six Pianos” and Julia Wolfe’s “My Lips From Speaking,” and much more of the most accessibly inventive modern music being created today.
