Nachtmahr is a group from Vienna, Austra that's fronted by chief singer/songwriter Thomas Rainer. Creating a slightly noxious and abrasive sound that blends elements of hardcore punk with techno, Nachtmahr released its debut album, Kunst ist Krieg (Art Is War), in 2007 and since then the group has distinguished itself with a controversial stage show that doesn't shy away from sexist and fascist themes.
