Commercial Breaks & Beats

I've tried all over to find out the music to the bbc climate change trailer (climatechange.gov.uk) to no avail. It's the one with the violins and mental grindy electro sounds - and says "..if we could see the gases we might do something..."
Any help appreciated.

It is a Live version of "P.S.I" by OSKAR (feat Sarah Willson and Ruth Gottlieb) - original version is on 'Air Conditioning' CD

That's the one! Thanks Keith - much obliged - kath.
