The Manhattan Transfer

There were several incarnations and formations of the Manhattan Transfer, with each rendition having different styles.
The first rendition was in the 1960s, consisting of a mostly an acappella-tinged style; it featured Tim Hauser, Erin Dickins, Marty Nelson, Pat Rosalia, and Gene Pistilli. The second version of the group, formed in 1972, incorporating a more vocal jazz approach, consisted of Hauser, Alan Paul, Janis Siegel, and Laurel Massé.
The third, and most commercially perceived, formation of the group happened in 1979, because Massé had to leave the group after being badly injured in a car crash and was replaced by Cheryl Bentyne. This edition of the Manhattan Transfer performed electronic-styled pop, soul, funk, and rhythmic music, having success in the 1980s.
Since the 1990s, the lineup of Hauser, Paul, Siegel, and Bentyne continued, and performed mostly cool and smooth jazz. The group also had several rotating touring members, and longtime pianist Yaron Gershovsky accompanied the group on tour and served as music director. Trist Curless from the Los Angeles a cappella group m-pact became a permanent member in October 2014 following Hauser's death. The group officially retired in 2023.
