Most rock and roll bands are a tightly wound unit that developed their music through years of playing in garages and clubs around their hometown. Steely Dan never subscribed to that aesthetic. As the vehicle for the songwriting of Walter Becker and Donald Fagen, Steely Dan defied all rock & roll conventions. Becker and Fagen never truly enjoyed rock -- with their ironic humor and cryptic lyrics, their eclectic body of work shows some debt to Bob Dylan -- preferring jazz, traditional pop, blues, and R&B. Steely Dan created a sophisticated, distinctive sound with accessible melodic hooks, complex harmonies and time signatures, and a devotion to the recording studio. With producer Gary Katz, Becker and Fagen gradually changed Steely Dan from a performing band to a studio project, hiring professional musicians to record their compositions. Though the band didn't perform live after 1974, Steely Dan's popularity continued to grow throughout the decade, as their albums became critical favorites and their singles became staples of AOR and pop radio stations. Even after the group disbanded in the early '80s, their records retained a cult following, as proven by the massive success of their unlikely return to the stage in the early '90s. In early 2000, the duo issued Two Against Nature, their first new studio album in two decades. In 2003 Steely Dan released another album, Everything Must Go. They have sold more than 30 million albums and continue to tour the world.
