Working against a restriction - for me - often produces greater things than getting rid of all boundaries.

Jon passes from Darkness to Light.

Free form jazz means absolutely nothing to me. Because there are no boundaries.

I love classical music I love the way it's worked... all those chord sequences so I often use that sort of effect in my solos.

I don't think the Bonzo Dog could have evolved in America, nor could the old Nice: because of their musical discipline. This is one thing that British groups do have, a sort of discipline. Sometimes it can get a bit soulless, but on the whole I think it's preferable to the American alternative.

Deep Purple is a damn good band and we've made a niche in rock 'n' roll history. Maybe not a huge one but enough to be very proud of.
