How about giving him a rock band t-shirt or hoodie from his favorite band? You can also consider gifting him a vinyl record or a CD from a classic or contemporary rock band. If he plays an instrument, you can give him sheet music or a guitar pick with his favorite band's name on it. You can even get tickets to a concert of his favorite band if they are playing nearby. Another idea is to give him a book about rock history or a biography of his favorite rock star.
Or you can get him a star map with an important date you share.
