Nikki Sixx (MTLEY CRE), Phil Collen (DEF LEPPARD), Sebastian Bach (SKID ROW), Sammy Hagar (VAN HALEN) and Tracii Guns (L.A. GUNS) spoke to SPIN.com about NIRVANA's classic 1991 album "Nevermind", which will be reissued on September 27 in both standard and deluxe editions to commemorate its 20th anniversary."Nevermind" is often credited for eliminating "hair metal" and introducing the world to the heavy rock sounds emanating from the Pacific Northwest that came to be known as grunge. Nikki Sixx (MTLEY CRE): "I announced the album before its release on [MTV's] 'Headbangers Ball'. I said, 'Here is an important rock album.' I never understood bands saying NIRVANA had anything to do with derailing their career. Maybe those bands just didn't have the goods. You can't pee like a puppy if you wanna run with the big dogs." Phil Collen (DEF LEPPARD): "At the 1992 MTV Video Music Awards, we were the sacrificial lamb it was NIRVANA, PEARL JAM, CHILI PEPPERS, and DEF LEPPARD. People were quite hostile towards us, which I thought was a joke a new kind of music comes out that's about you not wanting to be like anyone else and then you're narrow-minded? Unfortunately, we got lumped in with these awful hair bands, which we didn't really think we were part of any- way. So when NIRVANA came on, it was like, 'Yeah, it's gonna fuck us a bit,' but it was also great music. Tracii Guns (L.A. GUNS): "Pop metal at the time was getting so shallow and watered down. NIRVANA just reminded people how ballsy rock is supposed to be. I got a copy of 'Nevermind' from a friend a few months before it came out it didn't immediately grab me, but after about a week, I was completely sucked in. [U.K.'s] Kerrang! [magazine] ran a photo of me wearing a NIRVANA T-shirt onstage with a caption saying something like 'Uh oh, is this the new trend?' I really don't care what my hair-metal peers thought or think."
