Jack White "breaks things with a baseball bat" before getting on stage.
The 'Seven Nation Army' hitmaker does his best to get into a "frenzy" in order to have the excess of energy he needs to give a good performance.
Discussing what he does pre-show, he said:"I'm drinking a Red Bull, a shot of whiskey,.
"I'm backstage with a baseball bat breaking things. You have to work yourself up into a frenzy."
The 41-year-old musician sets himself rules when writing music because he doesn't like to have too much "freedom" and is currently trying to compose in "silence".
He told The New Yorker: "I'm going to try to write songs where I can't be heard by the next-door neighbour.
"And I want to write like Michael Jackson would write--instead of writing parts on the instruments or humming melodies, you think of them. To do everything in my head and to do it in silence and use only one room.
"[I use] four tracks. With computers you can use three hundred and ten tracks if you want to, but it's too much freedom.
"I always have my own rules, and I can bend them if I want. I can see the confines I'm working in, but nobody else knows I'm doing it."
And Jack admitted he sometimes dreams of being confined to one place for a lengthy period of time with "nothing" to do.
He said: "If I could just break my leg and be in the hospital for six weeks, what would it be like?
"Something about a room and a cot and a little space. You have nothing to do."
