In the 1960s, a choreographer with this surname revived two of their works for the Royal Ballet at the behest of former student Frederick Ashton. Nine women pile their heads in a pyramid in a choral ballet by that choreographer with this (15[1])surname that illustrates the Bride’s dread at her wedding. Two boys and a girl search for a tennis ball in a ballet by a dancer with this surname who originated the role of Petrushka. The choreographer of Poulenc’s (*) Les Biches (“le BEESH”) and Stravinsky’s Les Noces (“le NOHSS”) shares this surname with a dancer who originated the role of a Greek satyr who flirts with nymphs to music by Debussy. That man choreographed a ballet in which the chosen maiden dances herself to death. For 10 points, give this surname of Bronislava and her brother, the Ballet Russes choreographer of The Rite of Spring. ■END■
