John Mayer's debut presented him as the wide-eyed prodigy he was. It's a clever bit of counter-programming, because the guitar licks here and seductive tunes like "Your Body Is a Wonderland" are clearly the work of a musician wise beyond his years. If tracks like "No Such Thing" and "Why Georgia" likened him to Dave Matthews and David Gray, the jazz-fusion chords of "Neon" put him in a league of his own.
