What does a city sound like when you turn its transit system into a musical instrument? This clever web project answers that question by transforming the live movements of Los Angeles Metro trains and buses into an evolving ambient soundtrack. Every note is triggered by a real vehicle arriving at a real station, so the composition is constantly changing throughout the day.
Each rail and bus line has its own distinct synthesizer voice, creating a soundscape that grows busier during rush hour before relaxing into quieter, more spacious textures late at night. The geography of Los Angeles even influences the stereo mix, with eastern routes and western routes occupying different sides of the sound field, making the city itself part of the composition.
If you'd rather play composer than listener, the site's Conductor mode lets you customize instruments, adjust the mix, transpose notes, and even create your own arrangement to share. It's a wonderfully calming experiment that blends live transit data with generative music, resulting in a soundtrack that's never quite the same twice (and one that's just as enjoyable as background ambience as it is to explore on its own).
"This project was inspired by many sources, but to name just a few: the sound and music system from the game Mini Metro by Disasterpeace AKA Rich Vreeland, Brian Eno and Robert Fripp's work with systems music, and another live train data to music project trainjazz.com by Josh Wolk."
