The Super Audio CD (SACD) features two disc layers. One layer contains a standard version of the album that works on any CD player. The other layer includes high-resolution stereo and a 5.1 surround version of the recording that works on SACD-compatible DVD players and home theatre systems. Both layers employ SACD's Direct Stream Digital (DSD) encoding process that samples the music 64 times faster than CD for unprecedented fidelity.
One of the most famous albums of all time, Dark Side of the Moon
sold 25 million copies in its first 25 years of release. Dark Side of the Moon
was the first album that Pink Floyd decided to break in live before attempting to record, with the debut performance of what they then called Eclipse
just over a year before the final release date. When they finally retired to Abbey Road Studios with top sound engineer Alan Parsons, state-of-the-art 16-track recording equipment and the new Dolby technology to hand, it was to produce one of the great pieces of studio art. Covering a range of styles, this was the last album (prior to Roger Waters
' departure in the early 1980s) to whose writing the other members of Pink Floyd contributed significantly.
Nevertheless, it remains a stunningly coherent package, bound together by surreal fragments of speech (mostly gleaned from asking questions of the doorman at the studio) and Waters' bold and bleak lyrics. Often reputed to be about former member Syd Barrett's decline into schizophrenia, in fact Waters has said the lyrics "were a lot about ordinariness" and dealt with people's responses to the increasing insanity of the pressures of everyday life. Some of the extraordinary sound effects used came from the most unlikely sources--the coins at the start of "Money" from Waters tossing handfuls of change into an industrial food-mixer that his wife, a potter, used to mix clay. Whatever the medium, a new standard for attention to detail and production values had been set and the world of studio recording would never be the same again. --James Swift
