Following its debut a month earlier, Pink Floyd's Abbey Road-made masterpiece reached the Top spot of the U.S. Album charts on this date in 1973. Despite the fact that only two singles were released "Money" and "Us and Them", respectively, sales soared for the band's eight studio album. Dark Side of the Moon would only stay at #1 for one week, but its legacy was just beginning.
To date, the album has sold over 50-million copies worldwide and still holds the record by remaining on the Billboard charts for 741 weeks, or just over 14 years.
"It felt like the whole band were working together. It was a creative time. We were all very open." -Richard Wright.
