But that band was really just a recording vehicle for two songwriters from New York, Donald Fagan and Walter Becker, who would go on to create some of the finest albums of the Seventies and get inducted into the Rock Hall of Fame in 2001. But this first one has gone down in history as one of rock's finest. Randy Renaud revisits the birth of Steely Dan on this week's edition of the Chronicles of Rock.
