The 101 Plays Itself turns live traffic on Los Angeles’ Highway 101 into music. Every car captured by the Caltrans traffic camera becomes a musical note, creating a constantly changing soundtrack shaped by the actual flow of traffic.
This isn’t a prerecorded composition. The camera feed is live, and the timestamp is real. That means the music changes with the time of day: quiet and sparse late at night, then increasingly busy as rush hour approaches.
