I got a random tattoo the other day. It's a red triangle, which makes everyone think I'm arty, which I'm not. I used to draw red triangles all the time. It must mean something - maybe I don't know it yet. But I'll figure it out.

I think, it is a challenge to get critics or whoever to see past what you wear and makeup and the way you look and just concentrate on the music.

When I'm writing obviously I have all the nostalgia in the world, I have all the emotion in the world, but then when I actually perform, I need to just perform it, and that's it. I do retain like a little bit of it because I have to, I sing and perform the songs so I have to - it's a performance of the songs - but I just have to get the right balance.

Mumford & Sons' music appeals to a lot of America. I'm really proud of them.

I'm always intrigued by people that listen to my music, I just naturally want to get to know people who listen to my music because people who end up having such an attachment with my stuff, I wonder why they have such a connection to something that's so personal to me in the first place.

Lauryn Hill is quite political and is very bold and isn't afraid of wearing her heart on her sleeve, and same with Bjork, except she is a little bit more kind of fragile.

I started getting these attacks in 2009, just as my music career was taking off. I'd be doing photo-shoots and started to feel like I was having heart attacks. Increasingly I found it difficult to step outside my flat. Things started to get better after I saw a therapist, who told me I needed to make peace with my panic attacks.
