The Final Cut is the last Pink Floyd album to feature founding member Roger Waters, who went on to leave the band in 1985. It is the only Pink Floyd album without founding member and keyboardist Richard Wright, who had left the band under pressure from Waters after the Wall sessions. The recording was plagued by conflict; guitarist David Gilmour felt many of the tracks were not worthy of inclusion, but Waters accused him of failing to contribute material himself. The contributions from drummer Nick Mason were limited mostly to sound effects.

The Dark Side of the Moon explores themes such as conflict, greed, time, death, and mental illness. Snippets from interviews with the band's road crew and others are featured alongside philosophical quotations. The sleeve, which depicts a prismatic spectrum, was designed by Storm Thorgerson in response to the keyboardist Richard Wright's request for a "simple and bold" design which would represent the band's lighting and the album's themes. The album was promoted with two singles: "Money" and "Us and Them".

A Momentary Lapse of Reason received mixed reviews. Critics praised the production and instrumentation, but criticised Gilmour's songwriting, and it was derided by Waters. It reached number three in the UK and US, and outsold Pink Floyd's previous album, The Final Cut (1983). It was supported by a successful world tour between 1987 and 1989, including a free performance on a barge on the Grand Canal in Venice, Italy.
