Antonio Vivaldi's three-act opera Orlando Furioso is set to an Italian libretto by Grazio Braccioli and is based on Ludovico Ariosto's epic poem of the same name. The opera alternates arias with recitative, and is set on an island at an unspecified time. The story line combines several plot lines from Ariosto: the exploits of the hero Orlando are detailed, as well as the tale of the sorceress Alcina. Orlando is performed in this production by Sonia Prina, and Alcina by Lucia Cirillo. Recorded at the 43rd Festival della Valle d'Itria, this production is the first video recording of this rare opera. Subtitles are available on this release in Italian, German, English, French, Japanese, and Korean.
