How about creating a playlist of his favorite indie music and presenting it to him on a custom-made USB drive shaped like a cassette tape? Alternatively, you could also purchase concert tickets to his favorite indie artist or band. You could also get him a vinyl record of one of his favorite indie albums, or a subscription to a vinyl record club that specializes in indie music. Another idea is to get him a book on the history of indie music or a biography of his favorite indie artist.
Or you can get him a star map with the date when he was born.
