48. Esperanza Spalding, 'Emily's D+Evolution'
After a Best New Artist Grammy and the well-received Radio Music Society, bassist-composer Esperanza Spalding could have certainly carved out a perfectly mellow career as America's virtuosic ambassador between contemporary jazz, neo-soul and pop music. Instead, on her first album in four years, she bravely and brilliantly machetes through thornier paths, including math-metal shredding ("Good Lava"), Laurie Anderson-style vocalizing ("Rest In Pleasure," "Ebony and Ivy") and brain-boggling progressive-rock majesty ("Elevate and Operate"). This unclassifiable art-funk-prog-bop concept opus is about identity, an unflinching look at love as theater, simmering rage over dreams deferred and class privilege. "Farewell Dolly" yearns for a piece of the pie, but by album's end she's doing a dissonant yet enthusiastic cover of Veruca Salt's Willy Wonka lament "I Want It All" and taking the whole thing. C.W.
