The Los Angeles ensemble Wild Up, often calling itself a collective, creates, in its own words, "projects that live somewhere between new music and theater and performance art and pop." Wild Up has collaborated with various traditional orchestras, rock bands, and cultural institutions. The group was formed in 2010 by Christopher Rountree, who remains its artistic director. His aim was to gather a group of young musicians who would create new classical music events that would live in the context of popular culture, performance art, and the musical avant-garde. The ensemble has performed live film scores, including those for Under the Skin by Mica Levi and Punch Drunk Love by Jon Brion. Wild Up appeared on a 2019 recording of Christopher Cerrone's The Pieces That Fall to Earth, and in 2021, the group released Femenine, the first in a series of recordings devoted to Julius Eastman.
