Harrison Ridley Jr.

Harrison Ridley Jr. (October 22, 1938 – February 19, 2009) was an American radio broadcaster and music critic.

Life Ridley was the host of The Historical Approach to the Positive Music radio show on WRTI (90.1 FM). The "historical approach" Ridley took was to focus on one musician per show, sometimes on a specific period in the musician's career.

Dubbed a "walking encyclopedia of jazz"

Teaching and outreach Ridley did not use the term "jazz," opting instead for "this music referred to as jazz" or simply, "the positive music." He taught music history at Temple University and Villanova University. He specialized in Duke Ellington albums (he had more than 600) and Benny Carter (he had 200 Benny Carter albums).
