interesting hum from a freight elevator at The Kitchen (former ice house, current art space) in chelsea, new york city. intense bass rumble kicks in about half-way through. mono recording: homemade contact mic -> minidisc.
Oh yes, great depth to this sound, hope to use it in Scene 3 of Episode 21 of Ad Astral – Hierarchy: due out in September 2013. Credits will be in the shownotes. Many, many thanks. Dave Burnham http://www.adastralpodcast.com
