How about getting him a collection of CDs or vinyl albums from some of the top hardcore bands of all time? You can also consider buying a hardcore band t-shirt or hoodie he can wear to concerts or out and about. Another idea is to book tickets for him to attend a local hardcore show or festival. If he doesn't really listen to music anymore, perhaps getting him a book or documentary on the history of hardcore music would make a great gift.
Or you can get him a star map with the date when he was born.
