In its later years, the company had a two-year residency at Dia:Beacon, where MCDC performed Events, Cunningham's site-specific choreographic collages, in the galleries of Richard Serra, Dan Flavin, and Sol LeWitt, among others. In 2007, MCDC premiered XOVER, Cunningham's final collaboration with Rauschenberg, at Dartmouth College in New Hampshire. In 2009, MCDC premiered Cunningham's newest work, Nearly Ninety, at the Brooklyn Academy of Music. The company concluded its farewell tour on December 31, 2011, with a performance at the Park Avenue Armory. Artistic philosophy Collaboration Merce Cunningham Dance Company frequently collaborated with visual artists, architects, designers, and musicians. Many of Cunningham's most famous innovations were developed in collaboration with composer John Cage, his life partner. Cunningham and Cage used chance procedures to generate material, discarding many artistic traditions of narrative and form. Famously, they asserted that dance and its music should not be intentionally coordinated with one another. John Cage, after his death, was succeeded in the role of music director by David Tudor. After 1995, MCDC's music director was Takehisa Kosugi. MCDC commissioned more work from contemporary composers than any other dance company. Its repertory included works by musicians ranging from Cage and Gordon Mumma to Gavin Bryars, as well as popular bands like Radiohead, Sigur Rós and Sonic Youth. The company also collaborated with an array of visual artists and designers. Robert Rauschenberg, whose famous "Combines" reflect the approach he used to create décor for several MCDC's early works, served as the company's resident designer from 1954 through 1964. Jasper Johns followed as Artistic Advisor from 1967 until 1980, and Mark Lancaster from 1980 through 1984. The last Advisors to be appointed were William Anastasi and Dove Bradshaw in 1984. Other artists who have collaborated with MCDC include Daniel Arsham, Tacita Dean, Liz Phillips, Rei Kawakubo, Roy Lichtenstein, Bruce Nauman, Ernesto Neto, Frank Stella, Benedetta Tagliabue, and Andy Warhol. Chance operations Cunningham valued the process of a work over the product. Because of his strong interest in the creation of the choreography he used chance procedures in his work. A chance procedure means that the order of the steps or sequence is unknown until the actual performance and is decided by chance. For instance in his work Suite by Chance he used the toss of a coin to determine how to put the choreographed sequences together. Indeterminacy was another part of Cunningham's work. Many of his pieces had
