How about giving her a vinyl record from one of her favorite post-rock bands like Explosions in the Sky, Mogwai, or Godspeed You! Black Emperor. You could even get one of their albums signed if possible. Alternatively, you could get her concert tickets for a post-rock band that she's been wanting to see live. To make it more special, plan a date night around the concert or create a cozy atmosphere at home with some candles and drinks while listening to her favorite post-rock songs.
Or you can get her a star map with the date of your first kiss.
