Guitars and guns are strangely analogous, strings like triggers, notes like bullets, amplifiers the hot steel barrel of a loud report. But can the sounds issued forth by a guitar actually cause one human being to kill another?

There is little doubt that music is a catalyst for both action and change. A greeting card for all occasions, music can be a source of celebration, a call to arms, a gateway to nostalgia, or a soothing comforter.

The martial strains of Queen's 'We Will Rock You' spike our sporting events; Wagnerian marches herald the serious and studious business of the nightly news; the stately and poignant 'Candle In The Wind' or 'Gone Too Soon' accompany the tears at our funerals; 'We've Only Just Begun' underscores the joy of many wedding days. We use music like a medicine.

It is equally true that guns have shaped the history of nearly every modern civilization on earth. As agents of both expression and change, music and guns bear much in common.
