A spare and gorgeous sound installation by the do-all composer Ryuichi Sakamoto, Glacier is just one of the many highlights at the Drop. Held beneath and surrounding the High Line, this all-day festival is a lodestone of art, music, and fashion with a simple mission: to open perspectives and foster collaboration. Several artists participate in a live-painting performance, while Art for Progress uses recycled materials and shouted input to create fashion. There's also a curated DJ sets, food trucks, $2 brews from Beerlao, and 2012+, a special exhibition that looks to and beyond that red-letter date of metamorphosis with work by Yoko Ono, DJ Spooky, Mamoru Oshii, and nearly 30 others. Upstairs at 521 West 25th Street is an AREAWARE pop-up store featuring art and design by the American Design Club.
