An exceptional series, with exceptional artists! Nelson Freire, darling of the French, in Grieg's concerto; Alfred Brendel, for the culmination of a 60-year career devoted to the Viennese classics; the return, against the odds, of Murray Perahia; and Cecilia Bartoli's first Brussels recital, in Rossini, music in which she is so perfectly at home since her identification with La Malibran.
