"Brain Damage" is the ninth track[nb 1] from English rock band Pink Floyd's 1973 album The Dark Side of the Moon.
[4] When the band reconvened after the American leg of the Meddle tour, Roger Waters brought with him a prototype version of "Brain Damage" along with other songs such as "Money".
The lyrics' tongue-in-cheek nature is further emphasised by Waters' assertion in the 2003 documentary Classic Albums: Pink Floyd – The Making of The Dark Side of the Moon that not letting people on such beautiful grass was the real insanity.
The German literary scholar and media theorist Friedrich Kittler attaches great relevance to the song, referring to its lyrics as well as to its technological arrangement.
[5] In a 2008 paper in Journal of the Association of American Medical Colleges Fusar-Poli and Madini suggest that the song includes avant-garde techniques and philosophical lyrics can be approached and analysed from a psychological perspective.
The line "I'll see you on the dark side of the moon", which became a famous metaphor of human irrationality, expresses that madness is always present but invisible, waiting to be exposed.
