Pink Floyd fans are invited to celebrate the 40th Anniversary of the release of Dark Side of the Moon this Saturday night at 8 pm EST (12am Sunday in England).  The full album will stream in full online at pinkfloyd.com as fans share thoughts, memories and photos via Twitter using the hashtag #DarkSide40.

Over the next few months, Pink Floyd will also unveil 14 new variations of the original album cover on their website. The new variations are designed by Storm Thorgerson, who created the ‘prism’ artwork for the original album.

In September 2011, CDJ’s Paul Rappaport had the opportunity to sit down with David Gilmour and discuss Dark Side of the Moon on Gilmour’s houseboat/recording studio, Astoria.  Check out the video here >
