I'm not a huge fan of improv theater or improv sports or whatever because it still just looks like a tool. It looks like a technique to me.
I don't pay much attention to sports.
I was in Paris at an English-language bookstore. I picked up a volume of Dickinson's poetry. I came back to my hotel read 2 000 of her poems and immediately began composing in my head. I wrote down the melodies even before I got to a piano.
