You can hear a mysterious phone clip by calling a hotline

Today, Conor Oberst and Phoebe Bridgers have connected themselves with a project called the Better Oblivion Community Center, which Oberst had been retweeting from his own Twitter account.

Over the last month, the Better Oblivion Community Center has been creating a presence through a Twitter account, bench advertising, and a hotline where you can hear a mysterious recording at 785-433-5534. According to Pitchfork, a project under the same moniker is set to perform on The Late Show With Stephen Colbert tonight and CBS This Morning on Saturday.

Few details have been released about the project, so it’s unclear as to what exactly it could be. If you’d like to take a listen to the voicemail recording without having to pay long distance charges to the United States, check out the clip below.
