Music for 50 Carpenters

Here's a link to a piece put together by artist Douglas Henderson. There is an mp3 of an excerpt from the performance on the page. Just from the small section you can hear the intensity of the piece as there are both moments of hammering that democratize into white noise and others that organize and create a hierarchy of sound and varying intensities and timbres.

A blurb from his website:

Music for 50 carpenters is: "..A theatrical surround sound work enlisting 50 skilled tradespeople. Prying at Stockhausen’s convolution theory of rhythm and timbre, 50 hammers, 50 blocks of wood and some 4000 nails of varying sizes are brought to bear. Under the guidance of a job supervisor hundreds of hammer blows become waves of tonal murmur threaded with rustlings of nails in bags and occasional snarls of righteous indignation. The performers are organized into work crews with lists of tasks and schedules, and arranged in a circle around the audience. Toolbelts, sweat and lunchboxes are part of the score, and union regulations governing breaks and meals are observed"
