What is the song in the movie Battle in Seattle from minute 16:15?

I just saw the film Battle in Seattle on BBC iPlayer and absolutely loved it. The song around 16min 15s was totally up my alley and I simply cannot find which song it is. It is not in the OST lists on the web and I am out of ideas of where to look. Any ideas?What is the song in the movie Battle in Seattle from minute 16:15?
The music in the film is by Robert Del Naja and Neil Davidge. Del Naja is in Massive Attack and Davidge is co-writer/producer of Massive Attack.

The soundtrack work was credited as Neil Davidge and Robert Del Naja in an effort to differentiate the soundtrack/film scoring work from the brand name of Massive Attack.

With this info you might be able to track down that particular song you are searching for.

Good Luck.
