A lot of people get really stuck in this idea that everything's been done and there's nowhere left to go. Rock 'n' roll is almost the most conservative form of performance art: you play your guitar, these are the moves, this is what the songs are about, and this is the energy. I always felt like there's so many sounds to make and things to talk about in songs. There's more to life than 'I love you baby, la, la, la'. I approach it more like filmmaking: you would never say every film has been made. You just tell another story.
