Exactly 50 years ago today, on March 7, 1973, Pink Floyd took to the stage of the International Amphitheatre, Chicago, IL, USA, in celebration of the release of The Dark Side of the Moon, in a set spanning over 2 hours, featuring songs such as Echoes, Obscured By Clouds, When You’re In, Childshood End, Careful with That Axe, Eugene, and the entire Dark Side of the Moon album with the encore of One of These Days.

As part of the celebrations currently ongoing for the 50th anniversary of “The Dark Side of the Moon,” Mark Campbell, a budding fan of the band who was in attendance at the International Amphitheatre, has very kindly given us permission to share his collection of photos online for the first time.

These were taken exactly 50 years ago, on this date.

When sharing these photos, Mark had this to say: “ Fifty(!) years ago tonight, I saw Pink Floyd from the eighth row on their Dark Side of the Moon tour at the International Amphitheatre. The album had just been released a week earlier, so we had no idea it would attain such legendary status. These photos were taken by me with my cheap Kodak Instamatic and by my friend with his Nikon 35mm. It was back in the days before heavy security, when you could leave your seat, walk right up to the front of the stage, and take pictures. Back then, their stage set looked (and was) incredibly high-tech. Now it almost looks like a high school band. And I still wonder why the band didn’t cover up that stockyards-era ad behind the stage for the Sirloin Room restaurant. At the time, the staging was incredibly high-tech, but now, it looks pretty tame. I took these pictures from my 8th row seat.”

Our thanks go to Mark for allowing us to use his collection.
