Thirty years since the death of Kurt Cobain have not diminished the importance and popularity of his music, which is commemorated in a book written by his former manager, where there are the first testimonies about this "eternal artist".

"He had a sensibility that made people feel less weird, less alone," explains Danny Goldberg, who has been in the music business since the '60s.

Author or co-author of all the successes of Nirvana, Kurt Cobain killed himself on April 5, 1994 in his home in Seattle, in the northwest of the United States of America, where he originated, while the rock music group had become a global phenomenon in less than three years.

"His image in the media was somewhat distorted and associated more with his death than with his life and work," notes Sonic Youth, who fronted another independent rock group.

In his book "In the Service of the Servant: In Memory of Kurt Cobain", published this week, Danny Goldberg talks about an advanced musician for his time, a melancholic character with a lively and very humane spirit.

"His voice had an incredible soul," he says, adding that "he reflected vulnerability and affirmation like rarely anyone."

For him, Kurt Cobain's music continues to be heard around the world by a generation born after his death.

"He is an artist whose work is timeless," says Danny Goldberg, who met the American guitarist and composer in 1990, just before the release of the album "Nevermind", which skyrocketed Nirvana's popularity.
