Although sometimes grouped with Spyro Gyra, the Yellowjackets are actually one of the most creative regular groups in the "rhythm & jazz" genre. Founded in 1981 as an R&B-oriented band that starred guitarist Robben Ford, the group took a giant step forward when, after Ford's departure, altoist Marc Russo took his place. With original members Russell Ferrante on keyboards and electric bassist Jimmy Haslip, in addition to drummer William Kennedy, the band found its own R&B-ish sound, sometimes playing original compositions that sounded like Joe Zawinul at his most melodic. Starting out on Warner Brothers in the early '80s, the Yellowjackets moved to MCA/GRP in 1986, where they released a string of well-received albums. In the '90s, Russo chose to go out on his own, and his replacement, Bob Mintzer (on tenor and bass clarinet), added more jazz credibility to the group's music. They moved back to Warner Brothers in 1995 for several albums before moving the Heads Up label for the live two-CD set Mint Jam in 2002. 2003 saw the release of their first studio album in five years, Time Squared. Three years later, the band celebrated its twenty fifth anniversary as an ensemble with the relase of the live album Twenty Five. ~ Scott Yanow, All Music Guide
