Listening to Marvin Gaye's 1971 career-changing album, "What's Going On," you can't help but wonder if the soul icon's formidable talents also included psychic predictions. That's because his melodic treatise on war, drugs, poverty, spirituality and ecology still rings disturbingly true 40 years later. This super deluxe edition provides a true inside look at the making of "What's Going On," featuring two CDs, a vinyl LP, 14 unreleased tracks, rare photos from the original cover shoot and essays by Gaye biographer David Ritz and writer Ben Edmonds. A warmer, newly remastered version of the original album leads off the package on the first disc. The CD also includes outtakes, demos and the album's three mono single releases, which became No. 1 R&B and top 10 pop hits: the title track, "Mercy Mercy Me (The Ecology)" and "Inner City Blues (Make Me Wanna Holler)." Disc two comprises a funky jam session featuring such young musicians as guitarists Ray Parker Jr. and Wah Wah Watson and bassist Michael Henderson. Capping the set is the first 12-inch vinyl LP of the "Detroit Mix" of "What's Going On," Gaye's original, darker mix of the entire album.
