Part of what makes a musician or entire band good, particularly live, is confidence. Arrogance lacks the ability to recognize one's own limitations or someone else's greatness.
There's something to this "confidence" thing. It's the difference between the occasional players in the wedding band and the musicians in the bar band that want to punch you in the face with their music.
Arrogance is the province of the 13-year old who finishes a patchy solo, throws his hands in the air and yells, "Nailed it!"
