The reason why I love people and writing about them is because they don't always respond with hate and anger. If they did I wouldn't have a story to tell. Who wants to know about someone who was brutalised and became brutal? I'm interested in the exceptions.

After my second-to-last record 'The Greatest' I had gone on tour for a while and I didn't play an instrument for about five years. And I got kind of - it's not self-esteem or whatever or anger toward myself - but disappointed in myself that I hadn't been challenging myself to learn musically.

Our task of course is to transmute the anger that is affliction into the anger that is determination to bring about change. I think in fact that one could give that as a definition of revolution.

I did not think that I was angry but clearly anger was reflected in my writing. I did not think that I had been affected emotionally but it was clear from my writing that I was still very emotional about the trial some six months after it ended.

I guess lyrically they're similar because they're talking about escaping the kind of misery that likes company. 'The Last One Alive ' for me is very simple. It's just about alienation really that causes anger.

Being told about the effects of climate change is an appeal to our reason and to our desire to bring about change. But to see that Africans are the hardest hit by climate change even though they generate almost no greenhouse gas is a glaring injustice which also triggers anger and outrage over those who seek to ignore it.

Most men's anger about religion is as if two men should quarrel for a lady they neither of them care for.

I was able to do To Sleep with Anger a very powerful film about African Americans their spirituality and the things that happened within a small community and a family.

So I'm not worried about the emotions I carry with me because I'm happy that I have them I think it's good for the work I do. The emotions that are not healthy are the ones you hold inside like anger.

I think anger and laughter are very close to each other when you think about it.
