Opera in one act with prologue. Based on the production of the Vienna State Opera by Filippo Sanjust. Libretto by Hugo von Hofmannsthal

These recordings are with two different orchestras (Mahler 1st with the Chicago Symphony and the 8th with the London Philharmonic). Tennstedt's live performances are much better than his studio versions of the same works, and it's wonderful to watch him coaxing what he wants from the players. Even though he conducts from the score rather than from memory, he always seems to be directly connected to the orchestra in an almost magical way. The sound is good in both performances, and there is a sense, on both occasions, of being present for something quite special. These are great performances.

Eine Nacht in Venedig (A Night in Venice) is an operetta in three acts by Johann Strauss II. Its libretto was by F. Zell and Richard Genée based on Le Château Trompette by Eugène Cormon and Richard Genée. The farcical, romantic story involves several cases of mistaken identity. The piece premiered in 1883 in Berlin and then Vienna. It became one of Strauss's three most famous stage works and has been seen in New York, London and elsewhere, and has been adapted for film.

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.
