Howard Hanson, director of the Eastman School of Music, asserted last night that radio had "capitulated to greed" by turning over to advertisers network time formerly devoted to music. Hanson opened the Louis C. Elson Memorial Music Lectures at Paine Hall.

"We still have broadcasts of the Boston and NBC Symphony Orchestras, the Detroit Orchestra, the Orchestras of the Nation Series, and the Metropolitan Opera," he added. "But others of this kind have of late been abandoned in favor of advertisers or jazz orchestras."

"Equally unfortunate," the composer-conductor said, "are the results of a recent decision of the American Federation of Musicians which enables broadcasters to air the same program simultaneously over long wave and frequency modulation transmitters."

Commenting on the present boycott on recording, Hanson declared that it damages most the reproduction of serious music. "It takes away from the layman his most powerful means for the development of musical understanding."
