How about getting him a gift certificate to see a traditional music concert of his choice? Alternatively, you could try to find a vinyl record or CD of his favorite traditional music artist or band, or get him a subscription to a traditional music magazine or website. If he plays an instrument, you could also consider getting him a new sheet music book or replacing any worn out accessories for his instrument. Another idea could be to gift him a guided tour of a local historic music venue or museum.
Or you can get him a star map with an important date you share.
