Three years after the release of her celebrated debut album 19, Adele returns quite in style with her sophomore set 21. The LP represents the personal and artistic growth of the Grammy-winning vocalist. The offering's first single, "Rolling in the Deep," served as an adequate teaser for 21 which highlights the singer's personal experience with love - ranging from complete heartbreak to pure joy. NPR now delivers the opus in its entirety as a stream. The album hit the top spot in the UK its first week. The U.S. will see its release Feb. 22. Stream below.
