How about a vinyl record player and a collection of his favorite metal albums on vinyl? Or, you could get him tickets to a metal concert in your area. If he already has a collection of music, you could get him a shirt or hoodie from his favorite metal band, or even a metal-inspired piece of jewelry. Another idea could be a book about the history and evolution of metal music, or a subscription to a metal magazine.
Or you can get him a star map with an important date you share.
