Shelter is the result of an unusual collaboration among Bang on a Can's founding composers Michael Gordon, David Lang and Julia Wolfe. Scored for three sopranos and a 17-piece ensemble, the project explores what "shelter" means in different cultures. Ensemble Signal's debut recording, under music director Brad Lubman and producer Michael Riesman, was originally commissioned for the Next Wave Festival by the Brooklyn Academy of Music and premiered with Trio Mediaeval in Cologne, Germany in 2005.
