David Trujillo


circletwitterbird @davidtru08

He was afraid of the radio, but he let himself be taken by it. After studying journalism, he began to write in different Colombian and Latin American magazines about travel, ecology, gastronomy, culture, lifestyle, science and technology. He thought of pursuing a career in the film industry, but eventually he realized he preferred staying as a spectactor. He loves asking questions and listening to answers, so journalism has become his perfect tool to move around the world. He has been living in Bogotá for the last few years.

Weirdly, Ryan got his start in radio hitchhiking across the country. He took a mic and a recorder, stuck out his thumb, and went from New York to California interviewing everyone who gave him a ride. He learned how to produce audio stories at the Transom Story Workshop. He currently lives in New York, and is pursuing a masters in journalism at NYU.

Caro Rolando

Luis Fernando Vargas Vega

Editorial Assistant

circletwitterbird @LuisVarvega

Costa Rican. As a teenager he wanted to be a philosopher, yet he became a journalist. He has written about art, music, literature, and cuisine in various Costa Rican media outlets. He also studies social communication and is currently writing a thesis on anarchism. He reads to save himself, though he is not sure from what. He tries to find himself in Enrique Lihn’s poems. Fear takes over him when facing a blank page and he panics at the mere thought of driving a car. His life belong to two cats. He’s 24 years old, but many call him “Sir”: they have been very good or badly lived–the years–. He’s still undecided on that.

Andrés López

Production Assistant

circletwitterbird @Andres_Azpiri

When he was 10 years old and heard the song “Lemon Tree," he was sure he had to dedicate his life to music. When he turned 21, he spent a year in Germany playing in different venues and recording in the same studios as his childhood heroes. Once back in Mexico, he improvised his own studio that started growing once local bands chose it to produce their albums. In 2016 he remodeled the studio and El Limonero was born, where he produces and post produces audio for bands and films.
