“Intervention” is the first single released under the name Rella. Put out in 2019 following a heart-wrenching break-up, the song details the agony of someone falling out of love with you, and worse-yet, the agony of knowing you could run into that person at any moment. After being released as a single, it gained traction in the release of a compilation by Corkscrew Records. Additionally, it was featured in the film The Last Christmas Party, directed by Julian Santos and released by Four by Three Productions on Amazon Prime.
