Formed in 2005, Chiaroscuro Quartet comprises violinists Alina Ibragimova (Russia) and Pablo Hernán Benedí (Spain), the Swedish violist Emilie Hörnlund and cellist Claire Thirion from France. Dubbed "a trailblazer for the authentic performance of High Classical chamber music" in Gramophone, this international ensemble performs music of the Classical and early Romantic periods on gut strings and with historical bows. The quartet's unique sound—described in The Observer as "a shock to the ears of the best kind"—is highly acclaimed by audiences and critics all over Europe.
