I just got the first 6 lessons to the Outrageous Blues Lessons By Mail, yesterday. I had accidentally ordered the Advanced Jazz Lines, and so you sent me the Blues Lines for a nice price. Thanks. After looking through them and learning the first two I can tell that this is an extremely productive (and simple) way to master the Jazz-Blues vocabulary. Again I must say, What a great teacher, Robert! I can’t wait to add the entire series of lines to my toolbox of guitar tricks. Please Let me know the next time you guys have one of those BIG 30% off sales. Also looking forward to the next Source Code DVD, The Comping Expo.Joel Pipkin, PresidentChild Play Music Co.
