Dave Grohl is convinced he would still be making music with Kurt Cobain had the Nirvana frontman not met an untimely death in 1994.
During a special Apple Music Hits radio show celebrating the release of the new Foo Fighter's album Medicine at Midnight, Grohl opened up about the success of Nirvana and the unending grief Cobain's suicide caused him.
"Of course, it was an incredibly challenging experience [Cobain's death]," Grohl said.
"And ultimately one of the greatest heartbreaks of my life that Nirvana isn't still here today making music. Whether it would be called Nirvana or something else," he added.
"It is one of my life's greatest heartbreaks that Kurt isn't still here to write more amazing songs because it's pretty clear that he was blessed with a gift."
Grohl went on to call Cobain, who was found dead at his home in Seattle after checking out of a rehab facility, "the greatest songwriter of our generation".
"I'm very proud to say that I got to be his drummer and play those songs every night," he said.
The 'Everlong' singer said he originally wasn't sure if he would ever be able to join another band after Cobain's death, but was able to start forming the Foo Fighters as an outlet for his pain.
"I didn't necessarily want to just go join another band," he said.
"I was in mourning and just the thought of sitting down at a drum set or playing music, it just made me very sad.
"It was even difficult just to turn on the radio. I kind of blocked it all out for a while."
Grohl said that at first, he was recording songs on his own in secret, playing all of the instruments and singing.
"I was so insecure that I didn't want anyone to hear it, I didn't like the songs. I didn't like the lyrics [and] I didn't like my voice, but I felt like it was necessary as some sort of creative exercise or outlet," he said.
Medicine at Midnight was released earlier this month.
