I’ve now got a profile on Soundcloud where you can listen to some of my recordings — just some fairly old South American guitar recordings at the moment — along with some lo-fi phone recordings of the accompanying part from a few duets, so that a student can play along doing the melody part. I’ve put up Faure’s Pavane, the Beatles Here, There and Everywhere, and Empty Chairs and Empty Tables from Les Miserables in this format.
