Pharrell Williams just created a song that won’t be released for 100 years.

Pharrell Williams just dropped a new song but it won’t be released until 2117.

The song was premiered to only 100 people in Shanghai, China at a listening party thrown by Louis XIII cognac last Monday.

“100 Years” was recorded onto a record made of clay & stored in the cellars of Louis XIII in a state-of-the-art safe specially designed by Fichet-Bauche that is only destructible if submerged in water.

The whole idea behind the creation of the song is raising environmental awareness. Louis XIII and Pharrell Williams are looking to motivate people to take action against global warming & climate change. Many scientists have anticipated that a significant part of our world’s land (including where the song is stored) will be completely underwater in the next century, so, if the sea levels continue to rise, the song will be damaged.

In his statement to Vogue about the song, he said, “I want to be really clear that I am not a tree hugger. I think it’s important that every human being—from the most eco-aware person to someone that’s driving a diesel truck—always has a sense of terrestrial awareness. That’s what it boils down to.”

This isn’t the first time Williams takes a hard stance on raising awareness. At The 2015 United Nations Climate Change Conference, he called on world leaders to provide millions of green jobs around the world in order to tackle climate change & help create opportunities for young people in the process. Also, he made a green collaboration with the denim company G-Star (denim manufacturing generally has a large carbon footprint) & his Los Angeles home, which is built with locally sourced materials.

Pharrell Williams is not the only celebrity who pays special attention to the environment. The list also includes Leonardo DiCaprio, Emma Watson, Arnold Schwarzenegger, Emma Thompson, among others.
