Looking for a certain type of instrumental track
 

I'm putting together my own "soundtrack" for certain silent movies. And what I'm looking for is about a 4 or 5 minute long track that ends with a frantic climax. Similar to the end of Sigur Ros's "Hun Jord.." or the 16-minute mark of Godspeed/Emperor's "Canyons/static".

No metal or techno. Just Industrial,ambient,or Prog-rock. No lyrics, but maybe a scream or two. Thanks.

Just Like You Imagined by Nine Inch Nails

not sure if it's what you want, but it's the first that came to mind.
