I've played music somewhat seriously all my life and I spend significant time composing in my home studio. That background helps me to deeply appreciate the genius of Steely Dan's Walter Becker & Donald Fagin. Check out this video on the making of "Peg." It didn't just happy by putting a bunch of musicians in the room. They worked the shit out of that song to hone it exactly how they wanted it. For instance, they carted in 7 or 8 guitar players until they got the guitar lead the way they wanted it. And did you know that Michael McDonald did those exquisite background vocals? McDonald discusses his work on the background vocals at min 6:30. Enjoy . . .
