Törr is a black/thrash metal band from the Prague, Czech Republic, formed in 1977, and still going strong. Regarded by many as the fathers of czech metal, they have influenced a czech many other Czech bands. Originally their name was simply Torr like the old pressure unit. In 1981 they changed their name to Törr, inspired by the name of Motörhead. Törr also means "lame" in slang swedish, but this very probably wasn't intended.
