Above Griffith Park is the famed Observatory. There is a tunnel next to the building that travels approximately 60 yards through the hill. I wanted to investigate the acoustics of this particular tunnel as a possible venue for capturing unique sounds.
Equipped with a micro-cassette recorder I captured the sounds as noise would swell and recede with passing vehicles. The tunnel seemed to overload with thick beams of sound traveling through it. I became more intrigued by the tape hiss that slows down gradually with the dying batteries of the recorder. I fed the tape recorder back into Pro Tools patched through a tube compressor, to add warmth and limit the aggressive dynamics of the noise built up from passing cars.
