Starting today, Michael and Carissa Alvarado are taking fan submissions via Instagram and Twitter. Just tag your stories #PublicRecordEP, and they'll take them into consideration. You can also submit at PublicRecordEP.com.

"There are so many stories out there that are way weirder, wilder and more beautiful than anything the two of us could experience in our lifetime," the couple says.

The folk-pop recording artists will turn the four "most amazing stories" into songs, and the whole process will be documented on their YouTube channel starting in October. Special episodes will see Us the Duo travel to the winning storytellers' homes, where they'll debut the fan-inspired tracks in intimate performances.

Once all the songs have been written, the Public Record EP will be released.
