Boccherini and Gluck We're in concert with an orchestra called Europa Galante, and music by Boccherini and Gluck. It's a pair of encores from a concert in Germany. First, Fabio Biondi leads Europa Galante in a movement from Luigi Boccherini's Symphony, Op. 21, No. 5. Then we hear a short Allegretto from Don Juan, by Christoph Willibald Gluck.
