was less enthusiastic but nevertheless considered that he "had his triumphs" in the performance. After The Magic Flute, The Times called Davis "master of Mozart's idiom, style and significance", although Heyworth in The Observer was disappointed by his tempi, judging them to be too slow. In 1960, Davis made his début at the Proms in a programme of Britten, Schumann, Mozart and Berlioz. In the same year, he was appointed chief conductor of Sadler's Wells Opera, and in 1961 he was made musical director of the company, with whom he built up a large repertoire of operas, conducting in London and on tour. Grove's Dictionary of Music and Musicians wrote of this period, "He excelled in Idomeneo, The Rake's Progress and Oedipus rex, and Fidelio; his Wagner, Verdi and Puccini were less successful. He introduced Weill's Mahagonny, and Pizzetti's Assassinio nella cattedrale to the British public and conducted the première of Bennett's The Mines of Sulphur (1965)." Together with the stage director Glen Byam Shaw, he worked to present operas in a way that gave due weight to the drama as well as the music. In his early years, Davis was known as something of a firebrand with a short fuse in rehearsals, and his departure from Sadler's Wells in 1965 was not without acrimony. After he left Sadler's Wells, and being passed over as principal conductor of the London Symphony Orchestra, Davis was named chief conductor of the BBC Symphony Orchestra (BBC SO), effective September 1967. At first, in the general view of the public, his tenure was overshadowed, at least during the Proms, by the memory of Sir Malcolm Sargent. Compared to the "suave father figure" image of Sargent to the promenaders, it took some time for the much younger Davis to be accepted. The BBC's official historian of the Proms later wrote, "Davis never really identified himself with the Proms in the way that Sargent had done. Davis was uncomfortable with the traditional hullabaloo of the Last Night of the Proms and attempted, unsuccessfully, to modernise it. The BBC's Controller of Music, William Glock, was a long-standing admirer of Davis, and encouraged him to put on adventurous programmes, with a new emphasis on modern music, both at the Proms and throughout the rest of the orchestra's annual schedule. Following his tenure as BBC SO chief conductor, Davis served as chief guest conductor of the BBC SO from
