How about getting him a ticket to a rock concert that's coming to town? Or if there aren't any concerts coming up, you could get him a DVD/Blu-ray of one of his favorite bands' concerts that he can watch at home. Another idea is to get him a rock band t-shirt or hoodie of his favorite band that he can wear to concerts or just around the house to show off his love for rock music. Finally, you could get him a book on the history of rock music or a biography of his favorite rock star to read in his free time.
Or you can get him a star map with the date when he was born.
