The title of the popular trumpeter and composer's latest triumph is a wistful reference to a language created in the late 19th century (by Dr. L.L. Zamenhof, who used the pseudonym "Dr. Esperanto") to facilitate communication between people of different lands and cultures. It's representative of the unique vibe of the collection, which features distinctive Euro influences drawn from the realms of trance, electronica, and acid jazz, with dramatic orchestral touches as well. Before those kick in, however, listeners are treated to an extension of the old-school brassy soul of B.W.B., the Warner Bros. ensemble of Braun, Kirk Whalum, and Norman Brown.
