It was man vs. machine in a cutthroat piano recital. Italian - and human - pianist Roberto Prosseda faced off against Teotronico, a robot musician. The test of musical talent went down at a concert hall in Beijing, China. They each played works by Chopin, Liszt and Beethoven, and were judged by audience applause. Prosseda was at something of a disadvantage. He has 10 fingers to Teotronico's 53.
