The Yellowjackets' first release for GRP, Greenhouse, is a real gas. The disc starts innocently enough with "Freedomland," the kind of smart smooth jazz song that marked The Spin. It's on the following "Greenhouse" that listeners glimpse a change in the air: Strings (!) set the stage for dreamy, exotic jazz that melts in your mind, music that goes well beyond similar experiments on earlier Yellowjackets sessions. From this point on, the band travels back in time: Russell Ferrante's piano, the understated rhythm section, and Bob Mintzer's saxophones (Marc Russo had left, though Mintzer wasn't an "official" member yet) smoke with the fire of cool jazz.
