In the early 1990s, Monk composed an opera called "Atlas", which premiered in Houston, Texas, in 1991. She has also written pieces for instrumental ensembles and symphony orchestras. Her first symphonic work was "Possible Sky" (2003). It was followed by "Stringsongs" (2004) for string quartet, which was commissioned by the Kronos Quartet. In 2005, events were held all over the world in celebration of the 40th anniversary of her career, including a concert in Carnegie Hall featuring Björk, Terry Riley, DJ Spooky (who sampled Monk on his album "Drums of Death"), Ursula Oppens, Bruce Brubaker, John Zorn, and the new music ensembles Alarm Will Sound and Bang on a Can All-Stars, along with the Pacific Mozart Ensemble. Meredith Monk has been composer in residence for Carnegie Hall, concluding in 2015.
