Two key elements to the 'Palmieri' sound were trombonists Barry Rogers (who was very influential as well as guitarist Bob Bianco, with whom Palmieri studied harmony to the fourth chords sound that Palmieri is known for) and Brazilian-born José Rodrígues. Together they were responsible for many of the 'head' arrangements, mambos and moñas that the band recorded. George Castro (flute), Manny Oquendo (bongó and timbales), Tommy López (conga) and Dave Pérez (bass) rounded out the group. To this day, the group is known as one of the swingingest, most danceable, innovative and influential groups of that period.
