A great gift idea for your dad who loves Adele would be her newest album "30". You can buy him the CD or vinyl record, or even purchase it on his favorite streaming service. If he already has the album, you could consider getting him Adele's biography or a book about her music career. Another option would be to get him tickets to see Adele in concert the next time she comes to town (if he hasn't seen her live before).
Or you can get him a star map with an important date you share.
