Grunge's sound partly resulted from Seattle's isolation from other music scenes. As Sub Pop's Jonathan Poneman noted, "Seattle was a perfect example of a secondary city with an active music scene that was completely ignored by an American media fixated on Los Angeles and New York ." Mark Arm claimed that the isolation meant, "this one corner of the map was being really inbred and ripping off each other's ideas". Seattle "... was a remote and provincial city" in the 1980s; Bruce Pavitt states that the city was "... very working class", a place of "deprivation", and so the scene's "... whole aesthetic – work clothes, thriftstore truckers' hats, pawnshop guitars" was not just a style, it was done because Seattle "... was very poor." Indeed, when "... "Nevermind" reached number one in the U.S. charts, Cobain was living in a car."
