The format of musical structure that represented Esperanza Spalding’s 2010 release Chamber Music Society is one that is centuries old. It’s a presentation of music that had birthed itself in classical realms within a very intimate environment. Originally Spalding was looking to release that record as a double effort alongside a possibly more familiar sounding arrangement, made available for an additional audience, but success has left time as a premium and that project would wait to unveil itself, until now in the form of Radio Music Society.
