What is an LP?
Long play (LP) record albums are 33⅓ rpm vinyl Gramophone records (phonograph records), generally either 10- or 12-inches in diameter. They were first introduced in 1948, and served as a primary release format for recorded music until the compact disc began to significantly displace them by 1990.
