You know, concert etiquette today asks that audiences remain quiet during performances until the end of each piece. I’m not sure I agree with that. Sure, you don’t want to be obnoxious or in anyway bothersome to those around you trying to appreciate the performance. At the same time, as both a performer and composer myself, I believe it’s somewhat respectful to let the orchestra know you’re enjoying a performance as it goes.
That said, my apologies that I couldn’t find a video of this with less crowd and more music. 
It’s the Video Games Live performance of works from the Metroid series. Enjoy!
