I was listening to Miles Davis Blackhawk CD when it the exchanges between Wynton Kelly's comping and Miles' leads struck me. I then became very interested in Miles Davis, which led me to Trane, Bill Evans, and Cannonball. Shortly after, the book "Hard Bop" came out, which gave me information as to other great artists. For about 10 years, I could only listen to jazz. I collected everything I could find. Then for old times sake, I bought a Grateful Dead concert from their '72 Europe tour. I expanded my horizons with rock etc. I listen about 50/50 to jazz and rock now.
