Back in August 2013, I curated and hosted this short screening of Youtube videos at Machine Project in Los Angeles. From their site:
Bennett will present and lightly host ‘Coolest Sound Ever’ and Other Search Terms, a short mix of found YouTube videos that documents humanity’s numerous and mildly successful attempts to capture auditory phenomena on consumer grade video equipment and cell phones. From the mountains to the valleys, from the gongs to the Disney cruise horns, from the air raid siren enthusiasts to the castle cistern free jazz, this mix brings us close listening for the short attention span.
This event is part of Machine Project’s All-Echo Weekend, as part of the Echo Park Rising festival.
Here is that same set of videos as a Youtube playlist. (At the time of the original screening, none of these videos had ads on them. Since then some have been added.)
Other search terms include gong, organ, echo, noise, siren, horn, horn battle, yelling, reverb, and chanting.
