"The combination of words and music hit a peak," explained Gilmour. "All the music before had not had any great lyrical point to it. And this one was clear and concise. The cover was also right. I think it's become like a benevolent noose hanging behind us. Throughout our entire career, people have said we would never top the "Dark Side" record and tour. But "The Wall" earned more in dollar terms." As one of the blockbuster LPs of the album era (1960s–2000s), "The Dark Side of the Moon" also led to an increase in record sales overall into the late 1970s.
