Myles Kennedy, rhythm guitarist and vocalist of Alter Bridge, and Slash, quote from GlideMagazine.com interview
You know, I started off taking lessons from a teacher and he’d teach me how to read music on guitar and play like “Mary Had A Little Lamb” and that lasted a few months. And that just wasn’t going to work for me (laughs). I really wanted to play rock. I actually ordered out of the back of a magazine something called the Metal Method, which was by this guy named Doug Marks and that was how I learned to play. It was like this audio cassette with little pamphlet series. It worked great.
