What is the music being played in Shameless Series 7 ep 1 during the riot at the library?

There is a classical piece being played during the riot at the library. When Frank and Libby are being pulled apart by the police. Does anyone have a clue what it is? I think it is quite lovely, and was a great pick for that scene in the episode. Cheers from the states!What is the music being played in Shameless Series 7 ep 1 during the riot at the library?
The music is a classical piece by 'Gorecki - Symphonie Nr. 3'. Although you pronounce his name something more like "Goretsky". You can find a few versions of it (sung and arranged by different people) but a very good one to get would be the album by Kazimierz Kord %26amp; Joanna Kozlowska.



iTunes has one of the tracks online and should you want the full album it is often called the 'Symphony of Sorrowful Songs'.



Achingly beautiful stuff that once you've listened to it a few times it will never be forgotten - and I'm not even a classical buff, just recognised something stunning, so it was a pleasure to help somebody else find it too. All the best from the UK!
