Tracks like "Don't Stop 'Til You Get Enough," "Rock together with You," the title cut (all Top 10 singles), and "Burn this Disco Out" not only consolidated his dance-floor power, but showed just how soulful and varied his vocals could get on uptempo material. Artistic role models like James Brown and Jackie Wilson echo throughout the mixes, but these were Jackson's leaps forward. The addition of pure pop confection--Paul McCartney's "Girlfriend," Stevie Wonder's "I Can't Help It"--further fleshed out the star's young-adult persona and helped do Off the Wall among the much fondly remembered of all his solo work. This exclusive edition features two magic home demos and entertaining, insightful interviews of producer Quincy Jones and "Rock together with You" composer Rod Temperton. --Rickey Wright
