I recently arranged the Concerto for Two Violins, BWV1043 by J.S. Bach for two soprano saxophones and chamber ensemble (flute, oboe, clarinet, bassoon, french horn, trumpet, contrabass, and optional continuo), and this arrangement is now available for purchase in the Store section of this website. Although this particular arrangement is for a specific group of instruments, please email me if you are interested in an adaptation for a different orchestration and I would be happy to work that out as well.
