Even if you don’t like the sounds of The Manhattan Transfer, you have to give the group credit: the vocal quartet completely defined a popular jazz style. Even jazz neophytes are deeply acquainted with the band's flawlessly executed, sweet-as-sacharine four-part harmonies. Tim Hauser founded the group in 1972, and it quickly became a regular fixture in New York’s jazz and cabaret scene, winning countless pop and jazz Grammys, especially in the “Best Jazz Vocal Performance by a Duo or Group.” Nearly 40 years later, the quartet is still at it with a week-long run at the Blue Note that starts tonight. This track, a cover of the standard “Route 66,” was one of The Manhattan Transfer's biggest hits. You may not appreciate the fake strings and pure vanilla groove, but you must admit, those harmonies sure are pretty.
