John Also Bennett - The Chord of Columbus, Ohio (2010, Bureau for Open Culture)
Three tracks of harsh/ambient noise derived from field recordings of a singularly awful city. Unlike many field recording projects, focuses more on mechanical and electric droning sounds than traffic noise, etc. For when you need to be reminded how much you hate living in an urban area.
Thanks to this guy for uploading The Chord of Columbus, Ohio, a totally out of print field recording project of mine from back in 2010.
