There are two bands called Umlaut. 1) An indie band from Sheffield, England who released one single “Winter Coat”, in Oct 2005 on Fantastic Plastic Records then split up. The different members went onto form two other bands Situationists and Johnny Rocket & The Bang Bangs. 2) An anarchist punk/crusty/hardcore/thrash band from Finland. They are notorious squatters, and ride large motorcycles.
