How about gifting her a vinyl record album of her favorite alternative/indie rock band? You could even make it extra special by searching for a limited edition pressing or colored vinyl. Another option could be concert tickets to see her favorite band or a music festival featuring her preferred genre of music. Additionally, you could purchase a CD or digital download of a lesser-known indie band's album that she may not have discovered yet but would likely enjoy based on her musical tastes. Finally, a personalized mixtape or playlist of her favorite songs would be a thoughtful present that reflects your shared musical interests.
Or you can get her a star map with the date of your anniversary.
