It’s 35 years since cd players became available in N. America and Europe. I bought my first player on the first day. There were two models to choose from: one from Sony and one from Philips. I bought the Sony. Alas, the shop didn’t yet have any stock of cd’s to purchase. However, they took pity on me and loaned me one of the Dvorak cello concerto. A cd then cost £10, which equates to £33 in today’s money after allowing for inflation.
