We first heard this story a while back. At the time it seemed like a nice idea, though we suspected it was a passing whim.
Not only were we wrong, but James Murphy, formerly of LCD Soundsystem and a self described, producer, DJ and 'man about town' has revealed a video expanding on his idea.
That idea is remarkably simple; to have all the ticket barriers on the New York Subway play tones that are musically harmonious rather than the dull bleeps they currently sound. When 'played' in tandem, through people entering and exiting the stations, music-like tones will be heard.
It's a simple idea, and Murphy's video explaining his thoughts can be seen below. We really hope it works out, as it perfectly shows how considered sound design can be transform public spaces in an inclusive and inspiring way.
