Dave Grohl and Taylor Hawkins Talk Chris Cornell in New Interview

"Depression is a disease", Grohl said of Cornell and recently deceased Linkin Park frontman Chester Bennington.

"What a devastating way to have my eyes opened to how many lives around me, and all of us, have been touched by such tragedy", he wrote. The hardest part is when you lose a friend; I just always immediately think of their families and bandmates.

Now, Foo Fighters frontman Dave has added his voices to the legions of tributes that poured in following Cornell's tragic passing. He also scolded those who have used his brother's death as a source for conspiracy theories and "absurd conjecture that defy decency and continually attempt to blur the facts".

Grohl advises anyone who is or knows someone suffering from depression to seek help.

"All you can really do is just let everybody know that you love them and be there for them and also to remember them in a good light instead of a bad moment".

"But there are a lot of people that get through, that deal, and so, I guess, basically [we] are trying to reach out to them and also to be an example of 'you can walk through that.' Because a lot of people were there for us when we walked through our thing". And it ain't easy. Chris Cornell hanged himself in a Detroit hotel room on May 18. Dave Grohl and Taylor Hawkins of the Foo Fighters are among the latest to weigh in.

I truly couldn't believe the way you picked up and carried the message of doing push-ups for suicide prevention. Grohl and Cornell were contemporaries and brothers in grunge, having come up in the same scene that put Seattle and Olympia, Washington on the map in the '90s. "If it looks like someone is down, way down, check on them".

Cornell revealed that he removed himself from social media as a way to keep from "continually picking at the wound".

While a very sombre Hawkins adds, "Like [Dave] said, people [think], 'You've got it so together.' It just goes to show you, it doesn't matter what's in your bank account, or how many hits are on your YouTube page, or all that kind of crap - it all goes out the window if, like Dave said, you're not feeling right".
