Sometimes, I ask one, two, or more people just to sit in the audience and to listen to me with concentration as I play. It's stimulating for me, and I try to build up a situation like that in a recital with a live audience. This helps me to play in a way that electrifies people. Burkard Schliessmann
No more than a surgeon can operate while tweeting can you reach your potential with one ear in, one ear out. You actually have to reacquaint yourself with concentration. We all do. Samantha Power
