One dancer who trained with Balanchine and absorbed much of this neo-classical style was Mikhail Baryshnikov. Following Baryshnikov's appointment as artistic director of American Ballet Theatre in 1980, he worked with various modern choreographers, most notably Twyla Tharp. Tharp choreographed Push Comes To Shove for ABT and Baryshnikov in 1976; in 1986 she created In The Upper Room for her own company. Both these pieces were considered innovative for their use of distinctly modern movements melded with the use of pointe shoes and classically-trained dancers -- for their use of "contemporary ballet".
Tharp also worked with the Joffrey Ballet company, founded in 1957 by Robert Joffrey. She choreographed Deuce Coupe for them in 1973, using pop music and a blend of modern and ballet techniques. The Joffrey Ballet continued to perform numerous contemporary pieces, many choreographed by co-founder Gerald Arpino.
Today there are many explicitly contemporary ballet companies and choreographers. These include Alonzo King and his company, Alonzo King's Lines Ballet; Nacho Duato and Compañia Nacional de Danza; William Forsythe, who has worked extensively with the Frankfurt Ballet and today runs The Forsythe Company; and Jiří Kilián, currently the artistic director of the Nederlands Dans Theatre. Traditionally "classical" companies, such as the Kirov Ballet and the Paris Opera Ballet, also regularly perform contemporary works.
