I was fortunate enough to be able to interview Tony Kakko last April for college radio show I had at the time. Here's a "video" of it (though it is entirely audio). The interview took place on their tour bus, so there's a lot of noise from the AC, the engine running, and the rest of the band walking in and out.

That's cool. I'll check it out. I did the first ever US interview, possibly the first interview PERIOD with Tony, back in 97 or 98. Many years later, I actually met him, and he remembered me, which was nice. I'm not so into the band anymore, but those first few albums are powermetal classics, and their demo is better than anything they did after.
