Alicia Keys' sound matures
By ADRIAN RUHI | Nov. 14, 2007Alicia Keys has carried a piano prodigy stigma throughout her career, yet her two studio albums and Unplugged album were punctuated with a hip-hop edge indicative of her Harlem upbringing. But with her latest, "As I Am," Keys' sound matures, often reaching adult contemporary. It's her most mellow, most boring album, but it's still pretty good.
