Review: Gaucho was the seventh studio album from soft-pop-rock-jazzists and yacht rock pioneers Steely Dan. Released in 1980, they would embark on a tour to mark the record's arrival, and then vanish for 20 years. Or at least go on extended hiatus. That's not surprising, given the back story here, with widespread creative disagreements and a three-way legal battle with MCA and Warner Bros ensuing. And an original budget blown by the sheer scope of 42 musicians contributing to the work. The Lost Gaucho is almost an unplugged version of all that. These are the alternative versions recorded in the early sessions that led to the final LP. Broadcast on radio as part of the promotional campaign, they've been compiled on this joyfully smooth and seductive package, which fans need in their lives.
