134 is a crew based in the area Essen. For me they are the „Stadtwald-Crew“, because 45134 is the postcode for Stadtwald, situated in the south side of Essen, where I saw the 134 tag first. I don’t have hard facts due to the members of the crew. All I have, is the names of writers which are quoted due to the pieces I found over the time. And here they are, but, as always, no guarantee of completeness and no warranty of any kind!
