<human>:  What is the story behind The Wall by Pink Floyd?
<bot>: The Wall is a rock opera by the English progressive rock band Pink Floyd. It was released as a double album on 30 November 1979. The concept was based on the band's alienation from society, focusing on the character of Pink, an individual experiencing feelings of repression, disillusionment, and isolation. The album tells the story of Pink's life and struggles through many stages: the rock star, the husband and father, the lost soul stuck in the wild, and finally to the Madman. The storyline is revealed through a combination of fragmented memories, connecting pieces of the story together as a wall symbolizing psychological barriers. The album also features themes of conflict, death, pain, and oppression. At the end of the story, Pink manages to break down the wall, overcoming his isolation in the process.
