“We’ve lived with Songs in the Key of Life for 50 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 heads on tour starting October 13, where he’ll perform the album in its entirety. Full dates here.
