How about tickets to a concert of his favorite rock band or artist? Alternatively, you could consider getting him vinyl records or CDs of his favorite rock albums, a book about the history of rock music, a t-shirt or hoodie of his favorite rock band, or even guitar lessons with a well-known rock musician. You could also setup a day for him to visit a rock music museum or attend a festival that celebrates rock music.
Or you can get him a star map with the date when he was born.
