Looking back on the production of 'Nevermind,' I'm embarrassed by it now. It's closer to a Motley Crue record than it is a punk rock record.

Punk rock should mean freedom, liking and excepting anything that you like. Playing whatever you want. As sloppy as you want. As long as it's good and it has passion.

Rap music is the only vital form of music introduced since punk rock.

Play before you get good, because by the time you get good, you're too old to play.

Propriety is the new punk.

Punk is not just the sound, the music, punk is a lifestyle.
