When Steely Dan released *Aja* in 1977, the duo of Walter Becker and Donald Fagen had already built a reputation for obsessive studio perfectionism. With that album, they pushed their methods past the point of sanity, turning a single record into a grueling, year-long project spread across six different studios. The final album contained only seven songs, yet roughly 30 session musicians were brought in to complete them. The pursuit of one flawless take was relentless.

For the guitar solo on the track “Peg” alone, the band auditioned between five and eight different professional guitarists before settling on the single take they deemed acceptable. An entire week was spent chasing just eight bars of music. The effort paid off commercially. *Aja* became Steely Dan’s commercial peak, reaching number three on the Billboard chart and spending a full year inside the top 40, fueled by constant radio play.
The album is widely regarded as a masterpiece of polished studio craftsmanship. But the standard Becker and Fagen set for themselves proved impossible to sustain. The relentless pursuit of perfection exhausted the band creatively and physically. After *Aja*, it took three grueling years to produce a follow-up album.
That next project, *Gaucho*, proved to be the breaking point. The band collapsed during the making of *Gaucho*, with tensions and perfectionism taking their toll. By 1980, the group was effectively coming to an end, and in 1981, Steely Dan officially disbanded.
The masterpiece they built by refusing to compromise ultimately came at the cost of the band itself.
