French composer Léo Delibes's ballet +Sylvia originally premiered in June 1876 at the Palais Garnier, with choreography by Louis Mérante, and constituted a very loose adaptation of Torquato Tasso's 1573 poem Aminta. Though initially less than successful, it received renewed popularity during the late 20th and early 21st centuries thanks to periodic revivals. One such production, mounted by the Royal Opera House in 2005 for that institution's 75th anniversary, appears in this release. Presented in its original three-act form, it features dancers Roberto Bolle as Aminto, Darcey Bussell as Sylvia and Thiago Soares as Orion.
