How about a "Led Zeppelin: Album by Album" coffee table book or a vinyl record of her favorite Led Zeppelin album? You could also consider concert tickets to a tribute band or an upcoming concert of a similar artist. If your wife likes jewelry, you could also consider a piece of Led Zeppelin-inspired jewelry such as a necklace, bracelet, or earrings.
Or you can get her a star map with the date when she was born.
