One idea could be getting him a vinyl record of Nirvana's album "Nevermind". This can be a special and unique addition to his music collection. You can also consider getting him concert tickets for a Nirvana tribute band or a documentary about the band if he enjoys learning about their history. Another idea could be purchasing Nirvana themed merchandise such as a t-shirt, poster, or coffee mug. These gifts can also serve as a daily reminder of his love for the band.
Or you can get him a star map with an important date you share.
