Gregg Gillis, a.k.a. Girl Talk, recently took Rolling Stone writer Doree Shafrir on a tour of his computer and showed her how he puts together one of his albums — a method that he explains applies to his live shows as well. “It’s pretty thought out,” Gillis tells her. “But everything is executed on the fly. It’s like playing a song: You wrote the song, you rehearsed it, but you’re doing it live. There might be a little thing you do different night to night, but you are playing it pretty much the same way you always play it. Live, there’s things I give myself freedom on. If people are there and excited, then I can cut things, and just have melodies playing for a bit. And that changes from night to night.” Click through to watch the man in action.
