I've always been fascinated with the juxtaposition of technology in music, not only in recording, but in the keyboard. It's amazing the way you can apply technology to an art form.

We have always tried to treat every album differently and even from day one I think that each Asia album has been approached with care and thought and hopefully that shines through twenty years later.

With NOAH, you can create some stunning, yet original soundscapes. Therefore, as a performance tool, it really comes into its own because you can make one single performance which has a lot of detail.

Styx has their own style of music, and I think that's justifiable, the same way that Asia and Yes have had - Yes particularly has a unique style that seems to have transcended all styles of music for 43 years.

There is nothing like having your hands on a keyboard. Or an acoustic piano. Those are the things you can't really replace.

I think that Yes' music is kind of on its own out there, and it goes through different chapters, and that involves different people. I don't think it's a case of 'any year is better than any other.' They can all co-exist quite comfortably.
