Nigel Kennedy Four Seasons

It’s hard to imagine performances of Bach’s violin concertos like those of Nigel Kennedy or, now, these by Daniel Hope, passing muster two generations ago. But since then, Bach’s model, Vivaldi, has enjoyed a second rebirth through the midwifery of period instrumentalists who have sped up the tempos of his fast movements and shone light through the ingeniously transparent textures of his slow ones, all the while employing a wider range of colors than hitherto imagined.
