Emergence

The album era (sometimes, album-rock era) was a period in popular music, usually defined as the mid-1960s through the middle of the 2000s decade, in which the album – a collection of songs issued on physical media – was the dominant form of recorded music expression and consumption. It was driven primarily by three storage formats: the 33⅓ rpm long-playing record (LP), the cassette tape, and the compact disc (CD). Rock musicians from the United States and the United Kingdom were often at the forefront of the era.
