Doing things the way you see it, going by your own heart and soul, that is pure artistic integrity. Whatever the hair is six or sixty inches long, the eyes have make-up or not, the riffs are in 'E' or 'F' sharp, the amps are Marshall or not, all those things don't matter if you are doing it for the right reason, which to me means doing it for yourself
The music gets better and better. It ages so well. Some bands that you sit and listen to, and it just sounds completely silly a few years later, but that Nirvana stuff, when you hear it on the radio nowadays, it sounds as vital and vibrant as it did 10, 12 years ago, when it first came out. And one can only obviously wonder what other cool stuff would've come out of that whole thing.
