In case anybody was wondering what was he playing, it's a brazilian classical music composer: http://www.youtube.com/watch?v=jAg8VHuXNKU&feature=relat... - Choros nr1

http://www.youtube.com/watch?v=DDc230BMy8Y&feature=relat... - Choros nr10 (part 1)

http://www.youtube.com/watch?v=9GVWge4q8uc&feature=relat... - Choros nr10 (part 2)

Well and what could you expect from one of the greatest composers coming from the Brazilian musical culture? I accidentally started watching the Proms and was completely obliterated by that performance of Choros nr10, I had never enjoyed classical music that way.
