The Wall is a rock opera presented as a double album by Pink Floyd, released in late 1979.
Following in the footsteps of their previous albums, The Wall is a concept album - specifically, it deals largely with the theme of isolation from one's peers. This is largely inspired by their 1977 tour promoting the album Animals, with regards to an incident where Roger Waters' frustration with someone climbing the netting that separated the band from the audience reached a point where Waters spat in the fan's face. This led him to lament that such a wall exists, which in turn inspired him to base their next album on the theme of isolation from others. With this significantly darker theme, The Wall featured a notably harsher and more theatrical sound than their previous releases.

The Wall is a rock opera that centers on the character "Pink". Largely based on Waters' personal life, Pink struggles in life from an early age, having lost his father in war ("Another Brick in the Wall (Part 1)"), abused by teachers ("The Happiest Days of Our Lives"), nurtured by an overprotective mother ("Mother"), and deserted by his wife later on ("Don't Leave Me Now") - all of which factored into Pink's mental isolation from society, figuratively referred to as "The Wall".
