Manhattan Transfer: Tim Hauser, Janis Siegel, Alan Paul, Cheryl Bentyne (vocals). Additional personnel: Dean Parks, Jimmy Wyble, Steve Lukather (guitar); Jay Graydon (guitar, synthesizer, background vocals); Don Roberts (piccolo, tenor saxophone); Jai Winding, Bill Mays (piano); Greg Mathieson (piano, synthesizer, Fender Rhodes); Michael Boddicker (vocodor, synthesizer, vibrato); Ian Underwood (synthesizer); Andy Muson, Chuck Domanico, David Hungate (bass); Ralph Humphrey (drums). Recorded at Dawnbreaker Studio, San Fernando, California. This fourth album by the Manhattan Transfer was the first for Cheryl Bentyne, who replaced Laurel Masse after the original singer's auto accident and subsequent decision to leave the group. Though replacing Masse was difficult, Bentyne's energy and style proved to be the perfect complement to the group's already dynamic performance. Hits from EXTENSIONS include "Twilight Zone" and "Birdland," which earned the group their first Grammy for Best Jazz Performance, Vocal or Instrumental.
