John Clifford, born June 12th is the founder / artistic director of the original Los Angeles Ballet (1974–1985), and the chamber sized touring ensemble, Ballet of Los Angeles (1988–1991) and the creator of “CASABLANCA, THE DANCE” produced by Warner Bros.
 Theatre Ventures, Inc. (which premiered in Beijing, China at the historic "Great Hall of the People" in 2005) and his Los Angeles Dance Theater.
 Before that time,Clifford was a principal dancer and choreographer with George Balanchine’s New York City Ballet, (1966–1974) and guest artist from 1974–1980, and was widely considered to be Balanchine’s protégé (Saturday Review).
 He choreographed his first (of 8) ballets for the NYC Ballet under Balanchine at age 20 thus making him the 2nd youngest choreographer in history ever to be attached to a major company.
 The first was Balanchine himself who was 20 yrs-old when he choreographed his first ballet for Serge Diaghilev's "Ballets Russes."
 During his time with Balanchine, in his early 20's, he also was a guest choreographer with co's ranging from the San Francisco Ballet, to the Royal Winnipeg Ballet, to the Deutsche Oper Ballet in Berlin.
 Clifford's works were also featured in many TV shows and movies, such as "Flashdance," "The Man Who Loved Women," and TV series such as "Dynasty," "Glitter," and other shows produced by Blake Edwards and Aaron Spelling.
Russian Ballet is an artist's book by the English artist David Bomberg published in 1919.
 The work describes the impact of seeing a performance of Diaghilev's "Ballets Russes", and is based on a series of drawings Bomberg had done around 1914, while associated with the Vorticist group of avant-garde artists in London.
 Centred on Wyndham Lewis and Ezra Pound, the movement flourished briefly 1914–1915, before being dispersed by the impact of the First World War.
 The only surviving example of a vorticist artist's book, the work can be seen as a parody of Marinetti's seminal futurist book "Zang Tumb Tumb", using similar language to the Italian's work glorifying war, ("Methodic discord startles ..."), but instead praising the impact of watching the decidedly less macho "Ballets Russes" in full flow.
