Leland Cobain, the grandfather of late Nirvana frontman Kurt Cobain, has passed away at the age of 89. According to GrungeReport.net, the elder Cobain died in Montesano, Wash., on Wednesday (May 29).

The Seattle Weekly newspaper posted a feature on Leland Cobain in 2010 that described the singer's grandfather as someone who was willing to communicate with fans of the Nirvana frontman and welcomed them to his home to discuss Kurt. He turned his double wide trailer into a sort of mini-shrine to Kurt Cobain, with memorabilia and photos from his youth easily in view.

Leland was the one surviving member of the family open to hearing from Nirvana fans. He had theorized that his grandson was murdered, and did not commit suicide, and that left a strained relationship between him and other members of Kurt's family. An interview with Leland Cobain can be seen above.
