Pretty much everything you love about Stevie Wonder is here: romantic songs and social commentary; soaring ballads and badass funk. It features Stevie as a one-man band and also shows him collaborating with others (including backing singer Lani Groves, bassist Willie Weeks, and guitarist Dean Parks). He croons sweetly, and he belts it out with righteous fury. He gets experimental with the then-new ARP synthesizer, but also he also plays beautiful piano. And let’s not forget his relentlessly funky drumming.
