Document 5: ECM Records: ECM (Edition of Contemporary Music) is an independent record label founded by Karl Egger, Manfred Eicher and Manfred Scheffner in Munich in 1969. While ECM is best known for jazz music, the label has released a variety of recordings, and ECM's artists often refuse to acknowledge boundaries between genres. ECM's motto is "the Most Beautiful Sound Next to Silence", taken from a 1971 review of ECM releases in "Coda", a Canadian jazz magazine.
Document 6: Music Tapes for Clouds and Tornadoes: Music Tapes for Clouds and Tornadoes is an album by The Music Tapes, a project consisting mainly of Neutral Milk Hotel's Julian Koster, released in 2008 by Merge Records. Koster spent nine years recording the album using mainly antique hardware and such as a 1895 Edison wax cylinder recorder, a 1940's wire recorder, a "state of the art hard drive", and reel to reel tape recorders.
Document 7: Atlas (opera): Atlas is an opera in three acts composed by Meredith Monk who also wrote the libretto and choreographed the dances. It is scored for 18 voices and a small chamber orchestra which includes a shawm and a glass harmonica. The story is very loosely based on the life and writings of the explorer Alexandra David-Néel and is told primarily through wordless vocal sounds with brief interjections of spoken text in Mandarin Chinese and English. The opera was co-commissioned by Houston Grand Opera, the Walker Art Center in Minneapolis, and the American Music Theater Festival in Philadelphia. It premiered at Houston Grand Opera in February 1991, followed by performances that same year in Philadelphia and Minneapolis. It subsequently toured in the US and Europe and had its New York premiere in May 1992 at the Brooklyn Academy of Music.

Document 9: The Enchanted Island (2011 opera): The Enchanted Island is a "pasticcio" (pastiche) of music by various baroque composers, including George Frideric Handel, Antonio Vivaldi, and Jean-Philippe Rameau, devised and written by Jeremy Sams after "The Tempest" and "A Midsummer Night's Dream" by William Shakespeare. It was created by Julian Crouch and Phelim McDermott and premiered by the Metropolitan Opera on December 31, 2011, starring David Daniels, Joyce DiDonato, Danielle de Niese, Luca Pisaroni, and Lisette Oropesa. The popular 70-year-old Spanish tenor, Plácido Domingo, played the small but important part of the sea god Neptune. The following month a performance of the "pasticcio" was broadcast live into movie theaters across the world as part of the Metropolitan Opera Live in HD series. In late 2012, Virgin Classics released this broadcast version on DVD. The Met revived "The Enchanted Island" two seasons later. Daniels, de Niese, Pisaroni, and Domingo revived their roles from the premiere. Susan Graham assumed the role of Sycorax from DiDonato.
Document 10: Labyrinth (opera): Labyrinth is an opera in one act by composer Gian Carlo Menotti. The work was commissioned for television by the NBC Opera Theatre and uses an English language libretto by the composer. Unlike Menotti's previous television operas, such as "Amahl and the Night Visitors", this opera was written with no intention of being moved to live stage performance later. Menotti intended for this work to utilize the special effects unique to television which could not be recreated in live theatre. As a result, NBC's television production of the opera is the only performance the work has received. At its premiere in March 1963 the opera was mainly criticized by the press for its trite use of allegory and music which rejected the avant-garde in favour of romanticism. Critic Harold C. Schonberg stated in his review in "The New York Times" that, "Menotti falls back on the procedures he has always used: the scraps of canonic imitation, the stretches of parlando, the Puccini like melodies, the banal waltz themes... [It] ended up an allegory that had all the dimension of a Mobius strip: an example of slick television and cinema of the 1960s wedded pretty much to music of the 1890s... On the whole "Labyrinth" is one of the thinnest musical concoctions Menotti has ever put together.

The ensemble is noted for performances of works by composers based in the Philadelphia region, in particular George Crumb. Orchestra 2001 has performed many of Crumb's works since the ensemble's inception.

The orchestra has also premiered compositions by other composers such as:
