In the vast sea of faceless, average music that dominates today's landscape, a new Steely Dan CD is an incredible breath of fresh air. Even though Two Against Nature is immediately recognizable as the Dan, with it's  funked-up beats, arch lyrics, and cast of bizarre characters, it is still  an evolution of the sound that they've mastered. Dare I think it...there's  even a sense of wistfulness throughout this music, as Becker and Fagen move  into middle-age. Where they once pursued the co-ed in the first person (Hey  Nineteen), they're now using the third person to deal with the attractions  of the flesh (Cousin Dupree). Like all the music from Steely Dan, repeated  listenings bring new pleasure...20 years on I can still listen to Aja,  Gaucho or the Nightfly and make new discoveries...I'm sure 20 years from  now the same thing will happen with this masterpiece.
