Mercedes Díaz García possesses a natural intuition for musical phrasing, an authentic stage presence, and remarkable command over orchestral colors and dynamics. As an advocate for contemporary music, she has premiered numerous works by distinguished composers, including Leo Brouwer, whose Variaciones Concertantes was broadcast on Deutschlandfunk Kultur under her direction; Juan José Colomer, whose recent work Agony and Ecstasy she premiered at the Elbphilharmonie in Hamburg; and Margarete Sorg-Rose, whose Second Symphony she commissioned.
