Great live clips: The soundtracks of Harry Potter movies

To me, seeing music performed live, always adds an extra dimension to music; weather it is rock, jazz or classical music. It's a peak into what is really happening and all the details. This afternoon I have been watching some documentaries behind the scenes of the making of soundtracks for the Harry Potter movies, and they show this feeling at it's best. And oh, how I wish I could play a orchestral instrument. Maybe it's not to late?
