Steely Dan is a Grammy-Awar winning American jazz fusion/Rock band centered on core members Walter Becker and Donald Fagen. The band's peak of popularity was in the 1970s, when it released six albums that blended elements of jazz, rock, funk, R&B, and pop. Their music is characterized by complex jazz-influenced structures and harmonies, literate and sometimes obscure or ambiguous lyrics filled with dark sarcasm, and their adroit musicianship and studio perfectionism.
