Matthew Barley is a terrific Brit cellist. I love his CD Silver Swan, which I’ve had for a while. In terms of really fascinating and well-done multi-track recording, he’s right up there with David Darling and Maya Beiser.
I just came across his website. Fabulous. One of the best websites of any classical/post-classical performer I’ve ever seen (only criticism: if you are going to start a blog, then blog). And a great article on improvisation (which is how I found it).
