Clay has a presence on stage that is hard to put into words. He has grown quite a bit from the days of American Idol. There's not much to distract you from the pure singing performance during the concert. When Clay is on stage, your attention is drawn to him, and only him. Once Clay Aiken begins to sing, it's as if he becomes a part of the music. His eyes close, his voice comes out, and it really does feel like he's giving a part of himself through song. He has a powerful, powerful voice that carries far past the slight frame that stands on stage. His performance of 'Unchained Melody' was a really good example of this. When he belts out a tune, he really belts it out. There's a reason why people come to see Clay - he has a power to his voice that few can match. He might have lost to Ruben Studdard on the show, but his career after American Idol has proven which one was the real winner. Clay Aiken live in concert is something you really shouldn't miss.
