The Wall
As Pink Floyd's concepts grew more complex, their stage show became increasingly elaborate. Concerts regularly featured slide/light shows, animated films and a giant inflated jet that crashed into the stage. But the very stage show that was considered a band hallmark was fast turning into a source of frustration for the group's lyricist and conceptual director, Roger Waters. Pink Floyd concerts, Waters felt, had lost their intimacy and power to communicate. Ironically, Water's discontent fueled the band's biggest the concept album to date, The Wall. Simply put, the complex double-album set explored the relationship, or lack of one, between the star performer and his audience.
