Let's produce music.

(and other sounds too)
We help creators develop their projects with sound that engages emotion and represents their identity.
Some of our collaborators:
Backward Clock Sound is a certified provider of Apple Digital Masters
“Sound design is a way to elevate your ear fuzzies in any certain way to push and pull stories and emotions in all kinds of directions.” – Ben Fee

This is art.

Our mission is to foster a sense of collaboration. Whether it's audio mastering or complete sound productions, our purpose is to cultivate the trust necessary for creatives to develop their projects with a sense of support and constructive growth.

Backward Clock Sound is Jeremy Costa;  Montreal-born multidisciplinary artist, producer and sound engineer.

My strongest asset is my role as a collaborator in creative problem-solving. It's all about working together.

My diverse portfolio and varied skill-set has helped me hone in on the foundations of who I am; merging the mindset of a contemporary artist with that of an innovative audio engineer.

Andreas Helin
Creative Lead, Pinterest

"Jeremy is a musical magician. His energy and optimism make him a ton of fun to work with. In creating soundtracks for the Pinterest stories at Cannes Lions 2018, Jeremy delivered above expectations despite being on a tight timeline. Communication was exceptional throughout the project—working remotely and on a time-difference didn’t affect the day-to-day. He had the ability to handle more loose directions in combination with acting on very descriptive feedback. What I love the most was his enthusiasm to experiment with different genres in pursuit of finding the right vibe for the project."​


Dante Puleio
Artistic Director, Limón Dance Company

"A true artist of the highest caliber. Quality work, loves thinking outside the box, amazing to work with, excellent communication skills, timely delivery, and a kind and loving person to share space with."

"I worked with Jeremy for over five years. His patience, determination and well-rounded knowledge allows him to create timeless audio masterpieces that go beyond the average mix. He takes feedback like a champ and puts a piece of his heart into every track he touches."​

"Sound mixing can completely change the viewing and storytelling experience. Working with Jeremy is an amazing experience. He brings curiosity, interest, passion, love, and an insane amount of ability to the table. He not only understands direction in a storytelling sense, but he brings ideas that make the story much stronger overall. His sound design doesn't only feel like part of the entire process, but it feels like it adds so much more than a collaborator could dream of. His work isn't just great. It become necessary."
