If you could fuse together the Backstreet Boys and an East German Lutheran boys’ choir, you’d probably end up with something like Amarcord. This internationally acclaimed a cappella group owes much of its success, and its rich, engrossing sound, to Bach. They first met as choirboys at his old stomping ground in Leipzig and you can hear the influence manifest in a beautifully romantic sound that’s unique to the city: warm, deep and layered. Hear resounding and powerful interpretations of Renaissance madrigals, works by the great composers from the 18th and 19th Centuries, and new versions of folk songs from around the world
