 Busoni's international reputation swiftly rose and he frequently concertized in Berlin, the other European capitals and in European regional centres (including Manchester, Birmingham, Marseilles, Florence, and many German and Austrian cities) throughout this period, as well as returning to America for four visits between 1904 and 1915: his wandering life led van Dieren to call him "a musical Ishmael" (after the Biblical wanderer). The musicologist Anthony Beaumont considers Busoni's six Liszt recitals in Berlin of 1911 as "the climax of Busoni's pre-war career as a pianist".
