Inspiration comes to me all day long, every day.Sometimes when I'm falling asleep, I have these visions .But it's not just music―it's music, it's the clothing, it's the stage performance.Do you feel that you're more of a performance artist than a pop star?I certainly am a performance artist, yes.Yeah. And do you ever fear that what you got goin' today with your costume, your per no, I shouldn't say persona,because you are Gaga-your music, the entire package ... will it be able to stay there?
