David Van Tieghem (This Cat's Science is too Tight!)

Amazing.
From boingboing:

"In 1982, performance art percussionist David Van Tieghem coaxed sounds out of New York City streets. The resulting film, directed by John Sanborn and Kit Fitzgerald and aptly titled "Ear To The Ground," is a masterpiece. You might also remember Van Tieghem's name from his collaborations with Laurie Anderson. Ear To The Ground (YouTube)"

Boingboing, sooooo quality.
