Bagpipes are by no means commonplace in rock, but they're not totally foreign either. Korn has used them in several songs, and even AC/DC on their homage to young upstart rock bands on "It's A Long Way To The Top" from the Bon Scott years.
Check out this Scottish band cranking out this classic AC/DC track here.
Are you a fan of the bagpipe? Or only on St. Patrick's day?
