From Wikipedia
Innervisions is the sixteenth studio album by American singer, songwriter, and musician Stevie Wonder, released on August 3, 1973, by Tamla, a subsidiary of Motown Records. A landmark recording of Wonder's "classic period", the album has been regarded as completing his transition from the "Little Stevie Wonder" known for romantic ballads into a more musically mature, conscious, and grown-up artist.
