Alexander Bui was only four years old when his mother first taught him how to play the piano. She sacrificed her own time to teach Alexander. As a former graduate of the Vietnamese Conservatory she taught Alexander that it's not just about playing notes, but the music must have a meaning. Alexander says that playing the piano is just like any other sport, the more he practices the better he becomes.
Alexander plays the piano six to eight hours a day, and sleeps, eats and breathes classical music. He wants to prove that music is more than Lady Gaga. He wants to show America how beautiful and amazing classical music is. A few weeks ago, he was living a normal life, and now he has performed on one of the biggest stages in America.
