In 1973 Tharp choreographed Deuce Coupe to the music of The Beach Boys for the Joffrey Ballet. Deuce Coupe is considered the first crossover ballet. Later she choreographed Push Comes to Shove (1976), which featured Mikhail Baryshnikov and is now thought to be the best example of crossover ballet.[citation needed]
