CDs were developed by Sony in 1978. They were very expensive when they were first released, and I, a poor student at the time, couldn't afford them. This CD is part of an 80-CD collection of classical music titled "THE GREAT COLLECTION OF CLASSICAL MUSIC" (World Classical Music System) released by CBS Sony in 1980.
