Vaganova Academy of Russian Ballet
A video of the "La source" pas de deux taken from the 2008 graduation performance of the Vaganova Academy of Russian Ballet at the Mariinsky Theatre, St. Petersburg, may be found on YouTube, the choreography credited to Konstantin Sergeyev after Coppini and possibly created for Preobrajenskaya; the music is by Riccardo Drigo, composer of most of the additional dances added to the company's repertory in the early 20th century.
