"My interest in banjo began when I begged my parents to buy me a $70 dollar Harmony 5-string in 1974. I taught myself Scruggs style three-finger picking and a little of Pete Seeger's basic strum, and I was content with exploring mostly bluegrass until 1997. That's when I discovered, through an old high school friend, the joys of the clawhammer style. One of the most liberating aspects of playing clawhammer was recognizing the huge variety in old-time banjos. Gone was the slavish adoration of the pre-war Mastertone. Replacing it was the admiration of the minstrel oak hoop, the spunover rim with 50 hooks, even the bakelite rim of that old Harmony I still had stashed in a closet after twenty-five years. Because I happened to live about five miles from a gourd farm, I eventually decided to experiment with making banjos from gourds. Since gourds are relatively inexpensive, I learned a great deal through trial and error, and I documented the making of one on my website. This one went to the same old high school friend that turned me on to clawhammer."
