Violinist Michelle Makarski has pursued a varied career as a performer; she’s comfortable improvising and playing jazz, she is a champion of contemporary music, including works written especially for her, and she has a special place in her heart for JS Bach. Makarski and her friend Keith Jarrett collaborated on an appealing cd of Bach’s Six Sonatas for violin and keyboard on the ECM recording label. She spoke with Suzanne Bona from ECM’s offices in New York City. (Thanks to engineers Katherine Ariano and Rick Andress for their assistance.)
