I heard 'No One' from Alicia Keys a while ago and thought she was flat during many parts of the song. I just saw her new videoclip with Jack White and also thought she was really flat at some point. I checked many live performance on YouTube and she was also often flat. Is it me or she really has intonation problems? Does anyone on this board has worked with her in studio? I know Russell Elevado did. I'm wondering how she was in studio?
