The 50th-anniversary party for Stevie Wonder’s Songs in the Key Of Life continue this week with a limited-edition vinyl of the landmark 1976 album. The new color variant, available to pre-order now, combines the original 2LP vinyl with a bonus 7” “A Something’s Extra” disc.

Released on September 28, 1976, Songs in the Key Of Life featured some of Wonder’s most enduring hits, including “Isn’t She Lovely,” “As,” “Sir Duke,” and “I Wish.” The Diamond-certified record was the first-ever album by an American artist to debut atop the Billboard Hot 200, and only the third in history. It earned Wonder his third Grammy for Album of the Year, and was later inducted into the Library of Congress’ National Recording Registry. To this day, it remains the best-selling album of his lengthy career.

The special-edition vinyl is just the latest in series of celebrations spanning new releases, live performances, and more. On September 28, Wonder shared a new Songs in the Key of Life EP with four previously-unreleased recordings from the album’s original sessions: “It’s Easier,” “My Life Story of Love,” “I Can See the Sun In Late December” and “I’m Into Livin.” Wonder curated the EP himself, and mixed down the record with two of Songs in the Key of Life’s original recording and mixing engineers, John Fischbach and Gary O Adante.

“We’ve lived with Songs in the Key of Life for fifty years, but there’s still more to hear,” Wonder said in a statement. “We didn’t add these songs to the album, but they were part of what I was feeling and discovering as we made it. They bring me back to that time in my life, and now they get to become part of yours.””
Wonder will support the new EP—and the anniversary it marks—with a series of shows that will see him perform the album and its outtakes in their entirety. The Songs In The Key Of Life Performances kick off tomorrow (October 13) in Birmingham, England, and will eventually make their way stateside before concluding with a December 19 show in Los Angeles.
