All of Pink Floyd's 70s albums are a barometer of Britain's changing moods, as an age of optimism gave way to angst and apprehension. As the group evolved from the Flower Power world of their late-sixties music through the era-defining Dark Side of the Moon to the acerbic, late-seventies attitudes of The Wall, they became arguably the only British rock act to straddle the cultural divide between the swinging 60s and the post-punk 70s. In Pink Floyd's The Wall, Jeff Bench and Daniel O'Brien describe the making of The Wall—both the album and the film—and place it in the context of the changes in music and society which the album reflected. The book contains scores of rare color and black-and-white illustrations, including exclusive shots of the 1980 and 1990 live performances.
