Five Star Gift Ideas

If your grandpa enjoys experimental and avant-garde art or music, then here are some gift ideas that could match his tastes:

1. Membership to a museum or gallery that showcases avant-garde art. This would give your grandpa the opportunity to see new exhibitions, attend talks or events, and stay up-to-date with emerging artists.

2. A vinyl record or CD set featuring music by experimental artists such as John Cage, Morton Feldman, or Karlheinz Stockhausen. These musicians have contributed to the development of experimental and avant-garde music.

3. A book about experimental film or literature. There are many great books that explore this subject, from "Experimental Cinema" by Gene Youngblood to "The Theatre of Mixed Means" by Eugenio Barba.

4. A subscription to a magazine or publication focused on avant-garde arts, like "Artforum" or "The Wire."

5. An art piece itself. You could commission an experimental artist to create a custom piece for your grandpa, or purchase a limited edition print from a popular avant-garde artist like Yoko Ono or Jeff Koons.

Or you can get him a star map with an important date you share.
