Query: Explosive & Vibrant Performances

This must be one of the most exciting and powerful performances of Tchaikovsky's Concerto No.1 in recent decades. The phenomenally gifted Turkish pianist, Fazil Say gives incredibly dynamic and vibrant account of Tchaikovsky concerto and Liszt Bm Sonata both. The stature and maturity of his playing is comparable to the Russian masters. His tone ranging from massive and explosive fortissimo to ethereal pianissimo. What impressed me most is the fresh imagination and lyricism he injects into the both works. St.Petersburg PO's playing, under Temirkanov, is equally brilliant and powerful.
