Sofia Gubaidulina's international music festival is to be held in Moscow on October 23-31. The festival is timed to the composer's 70th anniversary. One of the most brilliant Russian composers of the 20th century Alfred Schnitke said about Gubaidulina, "She is incomprehensible, so she is a phenomenon." Graduate of the Moscow conservatory, one of the most performed modern composers, Gubaidulina has been living and composing music in a quiet German village since 1992. The festival will be held in the halls of the Moscow conservatory and in the hall of church synods of the Cathedral of Christ the Savior (Moscow's centre). The choir and orchestra of the Mariinsky theatre (St. Petersburg) directed by world-famous conductor Valery Georgiyev are to participate in the festival. The concerts of such outstanding musicians as Yuri Bashmet (Russia), Savai (Japan) and others are to be held as part of the festival in honour of Sofia Gubaidulina.
