Released in 1976, Chicago X is the tenth album by American rock band Chicago. The album reached the #3 position on the Billboard Pop Album chart and featured the band's #1 single If You Leave Me Now.
The album cover was designed by Grammy award winning American graphic designer and art director John Berg. The former creative director and vice president of Columbia/CBS Records, Berg oversaw the creation of countless album covers from 1961 to 1985. Berg did 14 album covers for Chicago before leaving his position at the label.
The cover for Chicago X is perhaps the one most often associated with the band. It was designed to look like a Hersey's chocolate bar, with the brand's trademarked brown and silver wrapper pealed back to reveal the name of the band embossed in chocolate. The album cover won a Grammy for Best Package Design in 1977.
I was in high school when this album was released and recall seeing several photographs of people pretending to be eating the giant chocolate bar LP sleeve. The joke just would not be the same with a CD.
