The highly distinguished conductor Rudolf Kempe (1910-1976) started as an oboist with the Leipzig Gewandhaus Orchestra. During the Second World War, he was chief conductor of the Chemnitz Opera until 1946. He then worked at Weimar for the 1948-9 season, before joining the Dresden Opera and becoming chief conductor. From 1952 to 1954, he was chief conductor of the Bavarian State Opera, which he conducted at Covent Garden in 1953 to great acclaim. Mahler's Symphony No.4 is a new addition to the Kempe discography. The recording, which was discovered in the Music Preserved archive in York, is a real rarity. Similarly, Mendelssohn's Ruy Blas Overture is a new addition to the conductor's discography. It is heard here in a fiery performance captured live from the Royal Festival Hall in 1967 with the LSO. Kempe's account of the Prelude to Act I of Wagner's Parsifal, recorded in 1965, confirms his status as one of the greatest Wagnerian conductors of the 20th century. His Covent Garden performances of Parsifal in 1959 were landmarks for the company.
