How about getting him tickets to see one of his favorite traditional music artists or a concert that features traditional music? You could also check out local events or festivals to see if there are any traditional music performances taking place in your area. Another idea could be to create a personalized playlist of his favorite traditional music songs and wrap it up with a card explaining the meaning behind the selection of each song. This way, he can enjoy the music anytime he wants and it will be a special reminder of your anniversary.
Or you can get him a star map with the date of your anniversary.
