Heads Up

Esperanza Spalding follows up the Grammy winning Chamber Music Society with a rangier CD that ought to bring her to the attention of an even wider audience. Radio Music Society is probably too sophisticated to fit comfortably into any traditional radio format, although it touches on several, including mainstream jazz, R&B and funk. The quiet, strings-enhanced balladry of “Cinnamon Tree” follows the bouncy “Radio Song,” laden with horns and vocal harmonies. Later, she connects with West African guitarist Lionel Loueke and the Savannah Children’s Choir for “Black Gold.” She slips into Stevie Wonder’s “I Can’t Help It,” with sometimes boss Joe Lovano on tenor and taps Q-Tip for both “Crowned & Kissed” and “City of Roses,” which is a salute to her hometown of Portland, Ore.
