Live performance from Salzburger Festspiele in 1987. Herbert von Karajan conducting the Wiener Philharmoniker and Wiener Staatsopernchor. Stage director Michael Hampe. Starring Samuel Ramey and Anna Tomowa-Sintow.

Soprano Yvonne Kenny turns in a spirited performance as Aspasia in this brilliant staging of composer Wolfgang Amadeus Mozart's first notable opera -- penned when he was only 14 years old. The production, set in early Roman times, follows the inner circle of the empire's most formidable foe, King Mithridates of Pontus. Maestro Nikolaus Harnoncourt conducts the sterling cast, which includes tenor Gosta Winbergh and mezzo-soprano Ann Murray.

Herbert von Karajan, who led the Belgian Philharmonic for more than three decades until his death in 1989, conducts this moving June 1985 concert filmed in Rome's breathtaking St. Peter's Basilica. Karajan and the orchestra take on Wolfgang Amadeus Mozart's "Coronation Mass," which displays the considerable talents of the composer and of Karajan himself, who managed to tease scores of emotion out of every note.
