Johnny Gandelsman, a co-founder of Brooklyn Rider and a member of Silk Road Ensemble, is used to playing music of many different styles—folk, jazz, contemporary, classical. Here, he returns to his roots for one of the masterpieces of the solo repertoire. His vast experience playing in so many genres pays huge dividends: This is music-making that feels both intensely new and satisfyingly old. The dance movements really do leap off the bows as his folk playing comes to the fore. A powerful recording that underlines Bach’s eternal relevance.
