Double bassist/vocalist and composer Esperanza Spalding may not be a household name yet, but many in the jazz world have already taken notice. She’s already worked with jazz heavies like Michel Camilo, Dave Samuels, Mark Walker, Byron Stripling, Regina Carter, The Boston Pops Orchestra, Pat Metheny, and Terri-Lynn Carrington, and performed solo (on vocals and bass) as the opening act for Bill Cosby. Spalding is the 2005 recipient of the prestigious Boston Jazz Society scholarship for outstanding musicianship and holds a B.M. from Berklee College Of Music where she currently teaches. She’s already toured throughout the world playing jazz, Cuban, R&B, bluegrass, Brazilian, hip-hop, and world music styles. Performing both original compositions and covers, it’s easy to hear why Spalding is making her own mark. Check out her arrangement of Egberto Gismonti’s “Loro” or her original composition, “Perazuán,” with its playful scat singing and teasingly syncopated interplay.
