Sparse sparrow, a heavy train, distant musical machine

Das Nasse Dreieck (The Wet Triangle) - formerly part of Berlin Wall death strip - is a rather hidden green space bounded on two sides by busy rail lines and and on the third by well fenced allotments. The entrance is tucked away out of easy sight and one gets the feeling that only locals know it. Kids play here after school - there is a great climbing tree - otherwise it is a dog walking domain. As the name suggests the ground is pretty soggy, pools form at the slightest suspicion of rain and footsteps squelch. Clumps of low trees and thorny bushes are home for chattering sparrows, crows, magpies. Trains sing and rumble past, a distant building site and bells sound from afar. The soundscape is fantastic. The presence of close birds, sub base freight trains and the distant city gives every mix from urban soup to transparent spatial perspectives. These recordings are selections from an audio stream running there for about 10 days. The mics were hidden in a clump of bushes often popular with sparrows. Rain crackles nicely on last year's dead dry leaves. Listening over such a period makes the features of urban daily/weekly cycles very audible. The dawn chorus, midday sparrow chatter, afternoon kids and late night train timetables are as regular as clockwork.
