"People often forget this - a vinyl album could only contain a maximum of 20 minutes per side!"

This quote by Ken Hensley is a pointer of the limitations of vinyl albums. In the past, plastic cds were the main means to listen to music. Nevertheless, because of the physical limitations of the vinyl document, each side of the album might only have an optimum of 20 minutes of music. This suggested that cds had to be split into 2 sides, with each side including a maximum of 20 minutes of music. This constraint was an obstacle for artists, as they needed to be innovative in exactly how they structured their music to fit within the 20 min time limit. It likewise meant that albums were frequently much shorter than they would have been if they had actually been launched on various other formats. This quote serves as a suggestion of the limitations of vinyl albums, and just how musicians had to be creative in order to take advantage of the layout.
