Dutch composer Thom Willems writes primarily for ballet. He has worked with William Forsythe since 1985, creating the music for more than sixty-five works. Until the late 1980s, Willems used sound recordings for his electronic music and musical collages, which he manipulated rhythmically. In the meantime, the composer works with state-of-the-art computer technology. His international breakthrough came in 1987 with the piece "In The Middle, Somewhat Elevated," which he created together with Forsythe for nine dancers at the Paris Opera. Other key works include the compositions for "LDC," "The Questioning of Robert Scott," "Eidos: Telos" and "Self meant to Govern." Thom Willem's works, in conjunction with Forsythe's choreography, can be seen in the repertoire of major ballet companies worldwide. In 1997, William Forsythe's short film "Solo" was presented with his music as part of the Whitney Biennial. In addition, fashion designers such as Issey Miyake and Versace use Willems compositions for their shows and in 2000 he composed for the opening of the Tate Modern in London. In 2007 Thom Willems was involved in Tadao Ando's research center for design "21_21 Design Sight" in Tokyo, in 2008 in Matthew Ritchie's installation The Morning Line for the Thyssen-Bornemisza Art Contemporary.
