How about a vinyl record of Nirvana's "Nevermind" album? It's a classic and I'm sure he'll appreciate having it in his collection. Another idea could be tickets to a tribute band concert that covers Nirvana's music. Alternatively, you could get him a Nirvana t-shirt or a poster of the band to decorate his space. Another unique gift idea could be taking him to visit the city where the band formed - Seattle, Washington - and checking out all the Nirvana-related sites and attractions, such as the Experience Music Project Museum.
Or you can get him a star map with the date when he was born.
