In a series of orchestral concerts in Berlin between 1902 and 1909, both as pianist and conductor, Busoni particularly promoted contemporary music from outside Germany (though he avoided contemporary music, except for his own, in his solo recitals). The series, which was held at the "Beethovensaal" (Beethoven Hall), included German premieres of music by Edward Elgar, Sibelius, César Franck, Claude Debussy, Vincent d'Indy, Carl Nielsen and Béla Bartók. The concerts also included premieres of some of Busoni's own works of the period, among them, in 1904, the Piano Concerto, in which he was the soloist under conductor Karl Muck; in 1905, his "Turandot Suite", and, in 1907, his "Comedy Overture". Music of older masters was included, but sometimes with an unexpected twist. For example, Beethoven's Third Piano Concerto with the eccentric first movement cadenza by Charles-Valentin Alkan (which includes references to Beethoven's Fifth Symphony). The concerts aroused much publicity but generated aggressive comments from critics. Couling suggests the programming of the concerts was "generally regarded as a provocation".
