PLOT
For those with any interest in Vivaldi's operas Orlando Furioso is essential viewing, being a 1989 San Francisco Opera revival by Pier Luigi Pizzi of his own 1979 production which was largely responsible for beginning modern interest in Vivaldi's stage work. The composer first premiered Orlando finto pazzo in 1714, but the Orlando Furioso finalised in 1727 was so heavily reworked as to be virtually an entirely new opera, and so successful Handel set the same epic poem by Aristo under the title Alcina in 1735.
