Virtuoso keyboard player though he was, J.S. Bach made sure he also had a second string to his bow—as a violinist. His six Sonatas and Partitas (suites) for solo violin were celebrated in their own time for educating as well as terrifying even the finest players. Zimmermann confesses to having waited until the fourth decade of his career to tackle them. His playing tells us that he positively relishes the challenge. He turns the final “Presto” of the Sonata No. 1 into a dizzying, helter-skelter ride where, despite the astonishing speed, he still manages to shape and color the music as it flies past. He brings a contemporary, almost minimalist, grace to the patterns of the slow opening movement of the Sonata No. 3, while injecting real dramatic thrust into the fast dances of the Partita No. 1.
