I started a quest to find terrific blues music and incredible musicianship when I was just a little kid. I also have a tremendous appreciation of fine musical instruments and equipment. One of my greatest joys all of my life was sharing my finds with my friends. I'm now publishing my journey. I hope that you come along!
