This session for the short-lived Mode label remains the zenith of Frank Rosolino’s recorded output. Paired with a stellar support unit featuring pianist Vince Guaraldi, tenorist Richie Kamuca, bassist Monty Budwig, and drummer Stan Levey, the trombonist not only delivers some of the most dazzling solos of his career, but also proves himself a gifted composer, contributing a handful of original tunes that fit comfortably alongside standards like Gershwin’s “How Long Has This Been Going On?” Largely eschewing more uptempo fare, Rosolino instead favors a simmering, soulful bop approach that champions feeling as much as technique. This is music with genuine emotional heft and intellectual edge. – Jason Ankeny
