How about some personalized blues guitar picks or a custom made leather guitar strap for his guitar? You could also gift him tickets to a blues concert, or a vinyl or CD of his favorite blues album. If he enjoys reading, you could give him a biography of his favorite blues artist or a book about the history of blues music. Additionally, you could plan a weekend getaway to a place with a thriving blues scene, such as New Orleans or Chicago.
Or you can get him a star map with the date of your anniversary.
