The flashy guitar player gets a lot of grease in this world. Well, I guess a good guitar player can be physically entertaining as well as agile. You never see a vocalist, for example, playing behind his head, or running slide bars up and down his throat.
Guitarists are rife with babes, gear-freak groupies, and curvature of the spine.
They also get a lot of ink. Most singers can't spontaneously sit in with just any band. The group has to fit in behind them, and know songs in common. Yet most professional musicians I've asked agree, there is simply nothing better than a good vocal to communicate and express feeling in music. Awash in guitarists, harmonica stylists, saxophone players, bassists and drummers, it's easy to forget vocalists.
