One idea could be to purchase tickets to a music festival or concert that he has been wanting to attend. If there isn't a music festival or concert happening that aligns with Christmas, you could also consider creating a festival-themed gift basket. Include some festival essentials like a portable charger, sunscreen, a pair of comfortable shoes, and a water bottle. You could also include festival gear such as a bandana or a hat, and some of his favorite snacks and drinks to enjoy while listening to music. Another idea could be to create a scrapbook of past music festival moments he has enjoyed, featuring pictures, ticket stubs, and other memorabilia from past festivals.
Or you can get him a star map with an important date you share.
