Best New Artist of the Year, according to the Grammys, is Esperanza Spalding, a 26-year-old jazz bassist and singer whose most recent album is titled Chamber Music Society. What!? or should the question be, How?! Full congrats, she’s as bright a rising star as has emerged from jazz by virtue of her charm and chops since 2006 — when Junjo, her first CD, was released. She beat out some kid named Justin Bieber, whose fans are enraged.
