Another form, Modern Ballet, also emerged as an offshoot of neoclassicism. Among the innovators in this form were Glen Tetley, Robert Joffrey and Gerald Arpino. While difficult to parse modern ballet from neoclassicism, the work of these choreographers favored a greater athleticism that departed from the delicacy of ballet. The physicality was more daring, with mood, subject matter and music more intense. An example of this would be Joffrey's "Astarte" (1967), which featured a rock score and sexual overtones in the choreography.
