The great violinist Victoria Mullova returns to Megaron, joined by the Scottish virtuoso pianist Alastair Beatson. Their program is dominated by Beethoven’s Sonatas no. 4 and no. 7. Both are a reference point in the repertoire for the two instruments, which are involved in dynamic arguments, mysterious whisperings, ecstatic exclamations and tender confessions. Making a great leap in time, the two musicians perform an ethereal work by the Japanese composer Toru Takemitsu and the mystagogical masterpiece Fratres by the Estonian Arvo Pärt, a work that established him internationally, unfolding a sacred ritual and a redeeming reflection on the simplicity and immediacy of sound.
