It currently exists on just 400 polycarbonate records — symbolizing the ~400 Sumatran tigers left in the world. Those records will degrade every time they are played until the song can no longer be heard.
"The song will go extinct unless it’s digitally produced. The Sumatran tiger will go extinct unless we take action."
400 people have received records, and they plan to digitize and share the song (and their conservation message). It’s a clever awareness campaign - and I’m looking forward to hearing the song!
