How about getting him a Guns N' Roses vinyl record of their debut album "Appetite for Destruction"? If he already has that, you could also consider getting him a band t-shirt or poster, or tickets to a future Guns N' Roses concert. Another idea could be a book about the band or a biography of the lead singer, Axl Rose.
Or you can get him a star map with an important date you share.
