STOMP Out Loud

I remember a similar scene copied in the advertisement of Abhishek Bachchan starrer movie "Bas itna Sa Khwab Hai" (2001). I was surprised and thought what kind of an idiot would go up high on structures like this to make some music ! But then I never knew about STOMP troupe. From the kind of music they produce, now I can understand why some one would do that :D Pretty impressive though.
