You may remember hearing about Esperanza Spalding at the 2011 Grammys when the relatively unknown jazz musician took home the prize for Best New Artist. After she won, many people were heard (and seen on sites like Twitter) wondering who she was. Well, she's back again to tell you! Her new album Radio Music Society is her poppiest jazz album yet and Spalding is preaching positivity with her smooth singing voice and amazing skills on both stand-up and electric bass guitar.

Spalding and her label released an official trailer to promote the album and it does an excellent job of whetting our appetites to hear more. If you want some more info on the album including a review and tracklisting, our friends at Steetdate have you covered. Here's the trailer for Esperanza Spalding's Radio Music Society:
