In an interview with Esquire UK Jack White made his feelings about Lady Gaga perfectly clear.
"I don't think she lives it because its all artifice. It's all image with no meaning behind it. You can't sink your teeth into it. It's a sound bite. Its very of this age, because I think that's what people want. They want a Twitter line, a jpeg, a MP3." He continued to talk about her music as insubstantial, empty music.
Can't say I disagree.
