Steely Dan is an American jazz rock band which formed in 1972. The band was formed by Donald Fagen (vocals, keyboards) and Walter Becker (guitar, bass), who met in 1967 while both attended Bard College in Annandale-on-Hudson, New York, and began a songwriting partnership shortly thereafter. Their music is characterized by dark, witty lyrical narratives, obscure lyrical allusions and complex, jazz-influenced instrumentation and chord sequences, overlying more ordinary popular song structures.
