Book excerpt: Written records of Alonso’s work are scarce, yet Toba Singer’s quest to spotlight his seminal role in the development of the modern ballet canon yields key material: pre-blockade tapes from Lincoln Center, Spanish-language sources from the Museum of Dance in Havana, and interviews with the ballet master himself alongside a broad range of friends, relatives, and collaborators from throughout his long career, including his ex-wife, Alicia, a famous ballerina in her own right.
