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.

Do you prefer Game OST music reactions only? Or is my gameplay streams also OK?🤷♂️
Ps. I’m trying to make sense of YouTube and how we should proceed so it’s a WIN for us all! 😋🌞

What kind of videos would you like to see on my channel in 2026? 🎻
Btw. I am gonna setup a notification system on my Discord so whenever I launch a livestream you will not miss out. 🥳 So make sure you are signed up there: discord.gg/NuZKEmffrg
I hear too many people don't get notices from YouTube when I launch streams. That's a real pity 😢
Tonight it's Dark Souls 3 stream at 09.00 PM CET! See you there!

Thanks to everyone who joined in on the Baldur's Gate 3 OST reaction stream yesterday! 🙏 Love the soundtrack! 💜 We're doing part 2 on wednesday this week. 🥳
Tonight it's a chill gameplay stream, gonna try streaming to YouTube and Twitch at the same time (restream) ...hope it goes well, it's been changing titles for no apparent reason, but I'll see if I can solve it this time. Wish me luck ! 😅
HAPPY NEW YEAR music lovers!
