In a new social post, the guys announced that they designed an app that is available via iOS and Android devices in which users are guided to local parks to enjoy  "Age of Man," the epic track opens their latest album Anthem of the Peaceful Army.

"We hope your ears are delighted by the introduction to our album, 'Age of Man,' when you embark on the White Rose March," said the band. "Appreciate the nature and experience an unreleased Greta Van Fleet song."

"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." Fans are then encouraged to take photos of their surroundings as well.

Try it out for yourself at this location.
