Becker met Donald Fagen while attending Bard College. The duo were part of Jay & The Americans for a while in the early 1970s, then formed the group Steely Dan in 1972. The band broke up in 1981, and Becker moved to Hawaii and began a career as a producer for a variety of artists, spanning from synth-pop groups to folk singers.
Walter Becker joined up with Fagen to collaborate on the debut album for Rosie Vela, and then for a longer time to tour as Steely Dan in 1993. The duo worked on each-others solo albums, Fagen's "Kamakiriad" and Becker's "11 Tracks Of Whack." Walter Becker is currently working on his next album in New York.
