Armenian-American violist Kim Kashkashian, one of the major musical voices of ECM New Series, introduces a new duo with Russian composer-pianist Lera Auerbach.

Their first recording together features Auerbach's viola and piano version of Dmitri Shostakovich's often playful 24 Preludes op. 34, and Auerbach's own, darker, sonata for viola and piano, Arcanum.

Lera Auerbach says, "Arcanum means 'mysterious knowledge', and I was fascinated by the inner voice within each of us, some may call it perhaps intuition, some maybe guided meditation, but there is some knowledge that we have, which we may not necessarily verbalize or rationalize, but that allows us to see the truth, to be guided, to seek answers."

Auerbach wrote her sonata for Kashkashian: "There is a quality of life-or-death-intensity to her performing, which is rare and wonderful."
