The Dark Side of the Moon is a 1973 concept album by Pink Floyd. It deals with the issues surrounding a normal person's life, such as time, greed, conflict, travel, mental illness, and death.

It is considered by many fans to be the band's magnum opus (surpassing even The Wall). It was a landmark in rock music, featuring radio-suitable songs such as "Money", "Time", "Us and Them", and "Brain Damage/Eclipse" that also incorporate ethereal concrete sound techniques. Some critics use the album as a point of reference between "classic" blues rock and the then-new genre of electronic music. However, the work's softer touches of lyrical and musical nuance are what make Dark Side stand apart from its peers. All four of the band members participated in the writing and production: David Gilmour, Nick Mason, Roger Waters, and Richard Wright.
