The YouTube videos of Evgeny Kissin and Yundi Li playing Liszt's La Campanella are often considered to be two of the top performances of the piece, although both are not without their detractors. Ludium Petroza recently wrote about the Kissin/Li wars and their impact on the debate about pianism in the July issue of Piano Pedagogy Forum. To see what he's talking about, be sure to click through to the YouTube pages after watching the videos and read the comments. Petroza makes an excellent point that YouTube comments are becoming a form of criticism in their own right.
