I've got my A2 music performance pretty soon and just found out that if I want to improvise for any part of it (which I do and have been practicing) I need the score to the backing track so they know what I'm playing over etc., and I cannot find any like this.

Can anyone help me out, it would be greatly appreciated

you havent searched to hard, you can google it and find a ton of free backing tracks
