Click to listen to Pink Floyd's 'Young Lust'
Pink Floyd's opus, The Wall, is now available in a special "Immersion" edition – 7 discs! – featuring video footage from the band's 1980 tour, a Behind The Wall documentary, a live recording of songs from the album and CDs of Roger Waters' original demos and the band's works-in-progress. Rolling Stone has an exclusive stream of the band demo of "Young Lust," one of the album's hardest rockers. The starker demo version emphasizes the song's funky bass line and a toned-down, almost relaxed vocal.
