What was very interesting for me, as soon as I saw the video, is that these guys are Irish! I could tell from the accent, but I looked a tiny bit into it, and apparently they actually did make the music for the Terry Pratchett animation trailer. Here's the official trailer: https://vimeo.com/88069708. I notice though, that the film's actual score was done by a different company. If this Xhail works out though, it could be great for low-budgets and students.
