Through the wonders of the Web, I can start to answer my own question. Benjamin even wrote a book on his pet topic:

Quote:
Benjamin, Edward B., Sr. The Restful In Music. New Orleans: Restful Music, 1970. 22 cm, 131 pp. Hardcover in full maroon cloth, top edge foxed, very good overall. "Millions of Americans resent the incessant yowling and howling of jazz, bebop and rock 'n' roll." Benjamin proposes as a cure the hundreds of soothing classical recordings detailed within, with discographical details.


I found this description on Ebay.
