The National Forum of Music (Narodowe Forum Muzyki) will be open in 2013.
It's going to be one of the most modern and prestigious concert halls in Europe. Here is a very interesting visualisation of the Forum.
The music in the background - Brahms' double concerto for violin and cello a-moll op. 102, vivace non troppo.
I can't wait to go to a concert there!:-)
