That outdoor place where band was assembled is called "Pakistan Monument" in capital Islamabad. It's a new'ish monument (built in 2007). bohat vadiya reaction c pai jan! <3
I don't think any culture gets better at the rate that Punjabis do. The goal is to evolve the music and still remain traditional. Nobody does that better than Punjabis, who else? Let me know below who is better at that?
