Cesare Siepi was an Italian opera singer, generally considered to have been one of the finest basses of the post-war period. His voice was characterised by a deep, warm timbre, a full, resonant, wide-ranging lower register with relaxed vibrato, and a ringing, vibrant upper register. Although renowned as a Verdian bass, his tall, striking presence and the elegance of phrasing made him a natural for the role of Don Giovanni. He can be seen in that role on Paul Czinner's 1954 film of the opera made during an edition of the Salzburg Festival under the baton of Wilhelm Furtwängler.
