By the early '70s, Stevie Wonder had grown restless with the Motown formula. Much like his friend Marvin Gaye, he'd discovered funk and psychedelic rock, and he felt a powerful urge to write songs that addressed social issues. Wonder unleashed one innovative album after another in the ‘70s, an astounding run that contained his funkiest grooves, most moving ballads, and catchiest pop hits.
