How about a vinyl record or CD from one of her favorite post-rock bands? You could even consider getting her an album from a lesser-known or up-and-coming post-rock group that she may not have heard of yet. Alternatively, you could get her a t-shirt, poster, or other merchandise featuring her favorite post-rock band. Another option would be a book about the history or importance of post-rock music, which would allow her to dive deeper into her passion.
Or you can get her a star map with an important date you share.
