Well I've only just confirmed for myself that Dias was the guitarist on Steely Dan's "Your Gold Teeth" on their "Countdown To Ecstasy". One of the best solos I've heard anywhere by anybody. If you play or like guitar, please listen to the track. Most likely you'll then want to hear the rest of his stuff. Incredibly lyrical with great texture and really interesting notes. Fagan's keyboard intro proceeding it ain't half bad either.
