Skins US - Characters' Trailers ...

Hey guys,

I was just wondering what's the name of the song in the first few seconds of each character trailer in the Skins US version?

<- (not the final song at the end, I know that song is by Sleigh Bells, but the beginning rough guitar tune?)

Any help would be much appreciated! Cheers
