Greta Van Fleet have released a single with a difference: the audio is only activated once you arrive at a local park. The single - and the instructions - are available from march.gretavanfleet.com, via iOS or Android devices.
"We hope your ears are delighted by the introduction to our album, Age of Man, when you embark on the White Rose March," say the band. "Appreciate the nature and experience an unreleased Greta Van Fleet song."
Fans accessing the URL on their smartphones are greeted by a message that reads, "We have a new song to share with you, and would like you to experience it in nature. If you share your location, we'll help you find the nearest park to listen."
Once fans arrive at their destination, the song is unlocked and they're encouraged to take photos.
The mobile app doesn't appear to be very good at identifying nearby green spaces, directing Classic Rock to a public square nearly a mile and a half away, despite there being a perfectly serviceable space within several hundred metres.
Fans have entered into the spirit of the launch, with one saying, "The park was empty and dark so I listened to the song while swinging on the swings. Haven’t done that since my kids were young."
Another said, "What you can't tell from this picture is how beautiful the moon was tonight. What you also can't tell from this picture is that right as the song faded, a double V of Canadian geese migrating south passed over... as we watched a shooting star crossed right under them. Thanks gents!"
Greta Van Fleet's debut album Anthem Of The Peaceful Army is out now.
