Klein's band, Big Van, includes four trumpeters, three trombonists, five saxophonists, a guitarist, plus the standard rhythm section. Klein composed, arranged, and conducted this ambitious and energetic music. "Abismo" is inspired by Poe's "Descent into the Maelstrom." The title cut and "La Manzana de las Luces" have stately openings that lead into the frenzied, passionate sound of the big band. "Primer Tango" points to Klein's Argentine roots. Klein's music is interesting and finely executed.
