This audiophile CD reissue brings back one of the Manhattan Transfer's more popular sets. Their hit version of "Birdland" opens the program, and among the other tunes are "Twilight Tone" and "Trickle Trickle." From the jazz standpoint, the most significant numbers are the catchy "Birdland," "Wacky Dust," Spyro Gyra's "Shaker Song" and "Body and Soul." Although not exclusively in the idiom, this release has enough high points so as to be easily recommended to jazz collectors. ~ Scott Yanow

This fourth album from 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.
