I definitely have a real self-destructive streak.

I have this sensation of being in flight all the time, but being on stage is like creating a sanctuary in which you can completely lose yourself. The bits of your personality that you keep under wraps in ordinary life, you can let them run free.

'Spectrum' is in part a disco song. But we play it hard, and it's a real euphoric, wailing tune. It's kind of like a total house anthem, in a way, but it seems to be going down really well. We've got all the grunge kids going mad for disco house raves.

During the songs, you transcend yourself. The best way to be in the performance is to be without pause and be essentially in the moment, in that moment of expression.

Being heartbroken is like having this really horrible freedom. You can be selfish with your thoughts, which can lead to manic creativity, but at the same time you're just really miserable.

I think an encore is perfectly acceptable, but I find it so weird when people do two or three.

When I am with my family, then I can just sort of switch off. It's kind of weird, because I go back and I go into this bedroom that I have had since I was a teenager. It is like this parallel universe, because one minute I am on the red carpet and then the next I am hiding out in this room I have had since I was 15.
