DePaul University Orchestra Director Cliff Colnot reorchestrated the Bottesini Concerto No. 2 back in 2008 for a performance with concerto competition winner Henry Chen. Cliff has made the score and parts to his edition of the concerto freely available.
Even better, Cliff had the DePaul Symphony record all three movements without the soloist playing, like a “music minus one” but with an entire orchestra! Here are MP3s of each movement. You can use these to practice along with. Very cool!
I’ll also add these links to the blog’s downloads page. Enjoy, and happy practicing!
