Stevie Wonder grew up fast, as Greatest Hits, Vol. 2 makes plain. Collecting both Motown assembly-line gems ("My Cherie Amour") and the first flashes of his self-contained '70s funk-rock style ("Signed Sealed Delivered I'm Yours," a terrific cover of the Beatles' "We Can Work It Out"), this 20-bit remaster disc is a must-own, particularly for Original Musiquarium fans looking for insight into Wonder's artistic growth. It's far from mere research material, though; the cream of this genius's early work is some of Motown's best. --Rickey Wright
