Premise: Pink Floyd . They gained popularity performing in London 's underground music scene during the late 1960s , and under Barrett 's leadership released two charting singles and a successful debut album , The Piper at the Gates of Dawn ( 1967 ) . Waters became the band 's primary lyricist and conceptual leader , devising the concepts behind their albums The Dark Side of the Moon ( 1973 ) , Wish You Were Here ( 1975 ) , Animals ( 1977 ) , The Wall ( 1979 ) and The Final Cut ( 1983 ) . The Dark Side of the Moon and The Wall became two of the best-selling albums of all time . The final Pink Floyd studio album , The Endless River ( 2014 ) , was recorded without Waters and based largely on unreleased material .
Hypothesis: Pink Floyd has an album.
