The older brother of Chuck Mangione, Gap Mangione has spent most of his career living in his native Rochester. During the 1960-65 period, the two Mangiones played together regularly in the bebop group the Jazz Brothers, recording three boppish albums for Riverside from 1960-61. When the band broke up, Gap stayed in Rochester, leading his own trio. After Chuck started becoming famous, Gap rejoined him on an occasional basis from 1970-72; however, he has mostly taught piano in Rochester since that time. As a leader, Gap recorded a pair of commercial big band dates (arranged by brother Chuck) for GRC in 1971 and Mercury in 1972.
