he said what the back track was a few posts up, lux aeterna from the requiem soundtrack. that was a cool video. song is nice too, used it on a presentation in college, it was cool because i talked about the romanticism (sp?) and about dark woods and shizzle, and the song breaks out in violins just as i talk about something sad, it was awesome. anyways, sorry to go a bit OT there. great vid.
