Radio K.A.O.S. is the second solo studio album by English rock musician and former Pink Floyd member Roger Waters. Released on 15 June 1987 in the United Kingdom and June 16 in the United States, it was Waters' first solo album after his formal split from Pink Floyd in 1985. Like his previous and future studio albums and many works of his during his time with Pink Floyd, the album is a concept album based on a number of key topical subjects of the late 1980s, including monetarism and its effect on citizens, popular culture of the time, and the events and consequences of the Cold War. It also makes criticisms of Margaret Thatcher's government, much like Pink Floyd's The Final Cut, another album conceived by Waters.
This 50-CD collection of analogue albums aims to represent the heyday of Philips’ passion for great natural sound – the Stereo Years. There was a firm belief within the label’s team that recording technique was there to serve the music - the Musicians had their own views about how any given piece should be interpreted and how it should sound; the recording team’s job was to grasp that vision and make it a reality. This recording philosophy, combined with great artistry and visionary repertoire policy, created a special chapter in the history of classical music recordings that still inspires artists, sound engineers and collectors alike.
