Album cover for Esperanza Spalding's forthcoming release "Radio Music Society"

The last album she put out was "Chamber Music Society" .. and the forthcoming release will be entitled "Radio Music Society" so you see there's a progression happening here..

from her interview with Billboard last March, she describes "Radio Music Society" as:

a "more upbeat and more sort of energetic" set that was conceived at the same time as "Chamber Music Society." "Originally I planned to release a double record, but that didn't work. The two (approaches) really couldn't be reconciled," Spalding explains. "So it became two different records. I just decided I wanted to do 'Chamber Music' first and then focus on 'Radio Music.' "
