How about a vinyl record by a post-rock band that your grandma likes? This can be a great addition to her music collection and can allow her to enjoy her favorite songs on a high-quality turntable. Some popular post-rock bands include Explosions in the Sky, Godspeed You! Black Emperor, and Sigur Rós. If she already has many records, you could consider getting her concert tickets to see her favorite post-rock band. This can be a memorable experience for her, especially if you can attend the concert together. You can also get her a book about the history and culture of post-rock or a poster of her favorite post-rock band to put up in her living room.
Or you can get her a star map with the date when she was born.
