He grimaces, he smiles, he swoons with the music up there on the podium, but this charismatic British conductor is more than just an able showman. His skill in the music of his compatriots, including Benjamin Britten and Thomas Adès, has impressed audiences across the globe—and even at the Philharmonie (also known as the House of Karajan). During Rattle's long music directorship of the Berlin Philharmonic, he's put on thrilling productions of the Bach Passions while also deepening the orchestra's engagement with modern and contemporary names like Bernd Alois Zimmermann and Georg Friedrich Haas.
