How about planning a surprise trip to Jamaica? There, you two could visit the birthplace of reggae and explore the music's history and culture. If Jamaica is too far, you could also try to find a local reggae concert or festival and take him there. Additionally, you could gift him some reggae vinyls or CDs, or even a reggae instrument like a guitar, to keep the reggae vibes going at home.
Or you can get him a star map with the date of your anniversary.
