How about a bluegrass concert or music festival ticket, if there are any in your area? You could also get her a gift card to a music store so she can purchase bluegrass albums or instruments to play herself. If she already has an instrument, you could gift her with bluegrass sheet music or a tutorial book to help her improve her skills. Another idea is to get her a bluegrass-themed t-shirt or hoodie. If she enjoys reading, you could gift her with a biography of a well-known bluegrass musician or a book about the history of the genre.
Or you can get her a star map with an important date you share.
