We craft dynamic, custom soundtracks for theatrical advertising, film campaigns, TV promos, video games, and advertisements—creating sonic experiences that captivate audiences and elevate storytelling.

Founded by Matthew Kratz (aka Kraddy), OBSIDIAN Audio combines cutting-edge creativity with industry expertise. Matthew’s career began as a trailblazing electronic music producer and founding member of The Glitch Mob, earning acclaim for his innovative sound and cultural impact. His iconic track “Android Porn” has surpassed one billion streams and remains a benchmark in electronic music.

Matthew has collaborated with artists such as The Beastie Boys, Sia, Korn, Rob Zombie, and Z-Trip, and his work has been featured in major campaigns for brands like Nike, Samsung, and Red Bull. His compositions have scored trailers for Dune, Top Gun: Maverick, and Bad Boys 4, among others. Notably, he composed a song for the Academy Award-winning documentary “Icarus” (2017).

At OBSIDIAN Audio, every project is a partnership where artistry meets precision. Whether it’s original compositions, covers, remixes, or overlays, our team is dedicated to delivering music tailored to your vision.
