How about getting your mom a vinyl or CD from her favorite post-rock band? You could also get her a poster or a t-shirt of her favorite band to show off her love for the genre. Another idea is to take her to a post-rock concert or festival in your area or buy her tickets to see a show that she's been wanting to see. Additionally, you could get her some music memorabilia from her favorite band like a signed vinyl, a limited edition release or a box-set of their albums. Another non-musical gift idea could be a book about the history of post-rock, or a book of photography that features some of the bands your mom loves. I hope these ideas help!
Or you can get her a star map with the date when she was born.
