I don’t know too much about Paraguay, beyond the fact that I want to visit it. The country is less of a mainstream tourist destination than its neighbors, Brazil and Argentina—which makes it all the more appealing to me. And after learning about the “Los Reciclados” orchestra,” I want to go there even more.

Just outside of Asuncion, Paraguay’s capital, is Cateura, a slum built upon a garbage dump. To give its young residents a hopeful alternative to the poverty and strife around them, local music teacher Favio Chavez started a youth orchestra—where every instrument is handmade from trash from the landfill.

Cellos are crafted from oil drums, flutes from water pipes. But what’s most astounding is how good these instruments sound. Check out the video below to see how Chavez and “Cola,” a trash picker, create the instruments, and hear the kids play—it’s truly amazing!

(Landfillharmonic, a documentary about the orchestra, is scheduled to be released next year)
