My aim is to be able to be more spontaneous so I keep evolving my live set-up.

You need to push yourself, put yourself in uncomfortable situations rather than stick to your comfort zone.

Sex is more openly spoken about than 40, 50 years ago, and I think probably in comparison to a lot of bands - certainly other contemporary pop girl bands - we're certainly not as suggestive. We talk about sex in the way that we would to our friends. As a girl group, I think it was important not to avoid those sort of things either, because it's about confronting people's idea of what women should be talking about and how they should talk about it. There's no point in shying away from subjects like that, because they exist.

We're more of a touring band than we are anything else, because it kind of all makes sense when we're on the stage. For us, success in America would be having as many people come to see us as they do in the UK and Europe, and I think anything that would surpass that would just be a surprise to us.

That you've got to do anything that you feel is precious. I especially believe that about cultures and languages. You've got to be really conscious because time is running out.

What playing solo has reminded me is how much I love electronic music and how much I love dance music. I'd like to move towards something more hypnotic and rhythmic rather than song-based.
