It's funny you make this thread now since a friend got me this band tshirt (pic related) because I "fixed" his computer (repairing grub ain't too hard with a bootable linux on usb key).
If you haven't heard of them, they're a breton punk band which actually uses a biniou which is some kind of bagpipe.
