Founded by record producer Lex Dromgoole, who’s shared his optimism about AI in music, and composer Gwilym Gold, Bronze makes tools that artists use to package music in a “generative, interactive, or personalized experience.” Bronze has tested its engine with Beatport, XL Recordings, A24 Film, musicians Disclosure, Arca, and Jai Paul, as well as Oscar-winning sound designer Nicolas Becker. Bronze says it worked with Chroma ahead of the acquisition on an app called “ Lux Aeterna,” a virtual world that offered an audiovisual experience designed for exploring the music from Venezuelan producer, DJ, singer, and songwriter Arca in a “meditative digital space.” The music reacts to changes in player movement, position, and activity, meaning users could fly through the virtual world, engaging with sounds as part of their journey. Investors include 14W, Adjacent, Hidden Ventures, Singular, Spoti Angels, plus Biz Stone and Pinterest co-founders Evan Sharp and Ben Silbermann.
