Luigi Boccherini
Luigi Boccherini (1743-1805) was an Italian cellist and composer. Perhaps his most famous work is a short movement from his string quintet in E, which has become known simply as Boccherinis Minuet.
A piano accompaniment track for that work is available on this website, along with accompaniments for his famous Cello Concerto in B flat, both in original form and the heavily altered arrangement made by Friedrich Grützmacher. Links can be found below.
