These jazz rockers loved their hard bop and cool albums. “Rikki Don't Lose That Number” nicks the slinky beat and piano from Horace Silver's “Song for My Father”, and their pop gems from Aja make ample use of the muted textures heard on classics like Miles Davis' “Freddie Freeloader”. But don't forget about soul; in Curtis Mayfield's “The Other Side of Town", Steely Dan found a model for shading complex arrangements with lush elegance.
