I watched this video with the typical ennui of your average internet user—expecting to hear nothing at all, really, before going back to other forms of online procrastination—but holy Hannah. This is a pretty loud building.
Although I would be making surreptitious ambient field recordings—and rhapsodizing to my sleepless friends about the unrealized acoustic dimensions of contemporary architecture—I have to say I'd be pretty unenthused to have this thing howling all day, everyday, in my neighborhood.
It's Manchester's Beetham Tower. It cost £150 million to build, and its accidental sounds are apparently now "the stuff of legend."
