How about a vinyl record of his favorite rock band or artist? You can also consider getting him concert tickets to see his favorite band perform, or a book on the history of rock music. Another option is to gift him a pair of high-quality headphones to enhance his listening experience. If your budget allows, you could also consider getting him a guitar or bass to encourage his musical talent.
Or you can get him a star map with the date when he welcomed you in this world.
