Back in the day, in '91 or so, I tried to interview Fugazi for Rolling Stone, which the band felt stood for everything they detested about corporate infiltration of music. They said, 'We'll do the interview if you give us a million dollars of cash in a suitcase.' Which was their way of saying no.

There's no law that says anybody has to do an interview.

To begin with, the key principle of American indie rock wasn't a circumscribed musical style; it was the punk ethos of DIY, or do-it-yourself. The equation was simple: If punk was rebellious and DIY was rebellious, then doing it yourself was punk. 'Punk was about more than just starting a band,' former Minutemen bassist Mike Watt once said, 'it was about starting a label, it was about touring, it was about taking control. It was like songwriting; you just do it. You want a record, you pay the pressing plant. That's what it was all about.'

People didn't get to see how other towns interpreted the underground ethos, and so they developed their own unique versions of it.

Just as not all popular albums are wonderful, not all wonderful albums are popular.

The online musical universe has become Balkanized, with many sites focusing on minute niches. That works well for reaching very specific demographics, which is wonderful for advertising, but it flies in the face of the common wisdom that people's tastes have become more diverse as music of any description has become a mouse-click away.

I'll leave it to other people to evaluate the legacy of my book, but I'm very moved when musicians tell me that they've been inspired by my book.
