From Wikipedia
Talking Book is the fifteenth studio album by American singer, songwriter, and musician Stevie Wonder, released on October 27, 1972, by Tamla, a subsidiary of Motown Records. This album and Music of My Mind, released earlier the same year, are generally considered to mark the start of Wonder's "classic period". The sound of the album is sharply defined by Wonder's use of keyboards and synthesizers.
