Though there's still much debate on whether to perform Bach keyboard works on period instruments or modern instruments, Murray Perahia was key in popularizing Bach performances on the modern grand piano. This reissue marks a decade since his performances of Bach concerti with the Academy of St. Martin in the Fields caused a stir. These recordings are still remarkable for their clean, decidedly Baroque restraint -- nothing too syrupy, too loud, or too inappropriately dynamic. Dispassionate? Hardly. Listen for the embellishments, where the pianist shows his colorful passion for the music.
