SNSD Demonstrates Their Professionalism Once Again @ the Summer Sonic Festival in Japan

Though there were sound issues during SNSD's performance of "The Great Escape," the members chose to continue singing. Thus, they proved their professionalism as idols and that they can sing live! Go SNSD! :D

(I just love SNSD's 1st Japanese album! Don't you? Personally, I think the songs are much better than the Korean ones they sing. No matter what, gotta <3 SNSD!)
