Kronos Quartet - Reqiuem For A Dream medley

I posted about the song "Lux Aeterna" from the movie "Requiem For A Dream" sometime ago, which I said it is an uncomfortable and disturbing song to me. I just found this video on Youtube, quite a recent one featuring the Kronos Quartet, the band responsible for playing the fearful song.

I warn you first, this is a song that doesn't really meant to sounds "nice", it's more to building up an uncomfortable & chilly atmosphere, which goes well with the movie's theme. The "nightmare" starts at the 1:25 part of the video....

Then at 4:20 is the best part of all.... Lux Aeterna.

Watch the video if you dare! :P
