Following hot on the heels of the album's ranking in the all-time top selling albums (see our news story of April 26th), Pink Floyd's Dark Side of the Moon achieved another impressive landmark this month.

Dark Side Of The Moon (30th Anniversary edition)

The 1973 classic has now achieved an incredible 1,500 weeks on the American Billboard charts since its release.

When it appeared, some 33 years ago, it spent its first 736 consecutive weeks on the chart until it dropped out in 1988.

Following another brief five week run, it has since dotted in and out of the top 200 for a further 759 non-consecutive weeks.

On being told of the 1,500 week landmark, Roger Waters told Billboard: "When the record was finished, I took a reel-to-reel copy home with me, and I remember playing it for my wife and her bursting into tears when it was finished. I thought, 'This has obviously struck a chord.' I was kinda pleased by that. I thought to myself, 'Wow, this is a pretty complete piece of work,' and I had every confidence that people would respond to it."

Waters will be performing the whole of ‘Dark Side of the Moon’ on his upcoming tour, with the help of Nick Mason on at least two of the shows.
