On banks I make no apology for attacking spivs and gamblers who did more harm to the British economy than Bob Crow could achieve in his wildest Trotskyite fantasies while paying themselves outrageous bonuses underwritten by the taxpayer. There is much public anger about banks and it is well deserved.

And I think there's something about conservatives frankly - and the Left when it comes to their channels of persuasion are unpersuasive. They are most of them are hate-filled obscenity-clogged rants of anger and hatred.

I don't play pyrotechnic scales. I play about frustration patience anger. Music is an extension of my soul.

I drank for about 25 years getting over the loss of my father and I took the anger out on myself. I did a good job at beating myself up at sometimes. I don't drink anymore but my alcoholic head occasionally says different. 'Nil By Mouth' was a love letter to my father because I needed to resolve some issues in order to be able to forgive him.

The great thing about celebrity culture is that they can't seem to stop themselves from displaying their ridiculous behaviour. I feel it's my job as a serious investigative journalist to witness all kinds of behaviour and then report back to the audience through the prism of my own anger and bitterness.

I've been trying to learn how to not be so conflicted about things like my own anger. I've always had a place in my music for my anger as a way of compensating for not having a mechanism to express it in my everyday life. So I've been trying to be more true to myself and that helps me to chill out a little bit. But politically uh-uh. No.

I think that Scottish people like Canadians are often misunderstood and what I like about my Scottish friends and relatives is how quickly it can go from love to anger. It's a great dynamic.

My dear brothers take note of this: Everyone should be quick to listen slow to speak and slow to become angry for man's anger does not bring about the righteous life that God desires.

What influenced me was Tori Amos who was unapologetic about expressing anger through music and Sinead O'Connor. Those two in particular were really moving for me and very inspiring before I wrote 'Jagged Little Pill.'

When someone says that I'm angry it's actually a compliment. I have not always been direct with my anger in my relationships which is part of why I'd write about it in my songs because I had such fear around expressing anger as a woman.
