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.

Thanks to everyone who manage to drop by last nights spontanous Game Music Show.😊 I had some initial problem with YT Music API changes, but with the help of AI got a quick Brave extension script working to get our nice music player up and running again in OBS!

What OST should we cover in the next Game Music Show?

Hey everyone! I’ve been away from streaming for a bit, and I’ve missed hanging out with you. Life, summer and projects pulled me in a few different directions, but I’m 400% excited to reconnect. Been practising some violin this summer, love the instrument. Also developed a fresh new synth, JORNA, it's sooo bad-ass, there's a 10-day free trial if you wanna check it out at your own pace: www.morningdewmedia.com/products/jorna/

This Wednesday we’re doing a fresh stream. I won’t spoil the theme, let’s make it a little surprise. Or do you have ideas? 😉 What would you like us to deal with in the upcoming game music shows?


Looking forward to seeing you again and picking up the creative energy where we left off.

Oh, and we have some cool stuff coming up next month too, also not gonna spoil. But I know you're gonna love the show... 🍿 To good healthy my friends!
