Commercial Breaks & Beats

Cheers for the advice, people (incidentally if it is Sigur Ros, its not on either Takk or Von, but these are the only 2 albums I have by them - any Sigur ROs fans able to help ?!) I'll check out the film tunes recommended though. Thanks.

Can anyone help with the piece of music used at the end of the new Dan Cruickshank modernist TV show (BBC2) shown this evening (9.5.06) ? This has also been used on Top Gear in the past but I just can't find anyone discussing it ?

Thanks
