As well as highlighting the dances, the book explores the contribution made by Ashton's collaborators, both designers and musicians. Central is the issue of identity and how style can be retained in dance, despite alterations in training. It considers the problem of how the values of ballet training change, thereby affecting contemporary performances of his works. Through eight works Morris examines the various sources that Ashton used, whether they were dances with words, or those influenced by dancers' movement style, jazz dance, abstraction, mysticism, or narrative. With this new material, the second edition makes a significant contribution to dance scholarship.
