Mattias Holmgren - Invidious

Mattias Holmgren

What happens when a pro composer hears your favorite game music?
I’m Mattias Holmgren (aka Gelhein), a Swedish producer and designer with 25+ years of industry experience. On this channel, I take deep-dive reactions into Game OSTs, breaking down the composition, sound design, and emotional impact from a professional perspective.

Beyond the music, I’m here to guide YOU in music production and creativity. I share the tricks I’ve learned over two decades to help the next generation of creative producers.
