Young Spanish conductor Pablo Heras-Casado gets around. He's the music director of the orchestra on this new recording of Tchaikovsky, but it's as a guest conductor where Heras-Casado is making his mark. He's omnipresent with the great orchestras of London, Vienna and Berlin. And while the Orchestra of St Luke's is a fine group, I can't help thinking that the next major opening will be his for the choosing.
