Here are some ideas:
1. Concert tickets: Buy her tickets for her favorite rock band/artist, or one she’s been wanting to see for a long time.
2. Vinyl records: Consider getting her an album by her favorite artist(s) or a classic rock album she hasn't yet.
3. Merchandise: Get her a band t-shirt or any other merchandise from her favorite rock band, that she could wear.
4. Books: Look for books about rock music history or biographies of her favorite artists.
5. Headphones: Get her a good-quality pair of headphones, so she can enjoy her favorite tunes without any disturbance.
6. Musical instruments: If your mom is musically inclined, you can get her guitars, drum sets, or any instrument of her choice.
7. Music documentaries: Get her a DVD or a subscription of music documentaries that she can enjoy watching.
8. Personalized rock music playlist: Make a playlist of her favorite rock songs, or add your favorite songs and personal messages that remind you of her.
Or you can get her a star map with an important date you share.
