Hello,

does someone know the composer and/or performer of the music of the GOG launch trailer, or where I can get the track?

Thanks

Seems you will need to ask them directly. http://shadwen.com

Alas, I didn't find any way to contact them on their website other than an e-mail newsletter (two-way?) whose subscribe button leads to an error message saying "We can’t connect to the server at sendy.frozenbyte.com."

Hello again,

I made e-mail contact with Frozenbyte. They were very friendly and helpful. With their explicit permission, I'll share the following with the GOG community:

The music is composed by Sauli Lehtinen, Frozenbyte's audio team leader. The song is a waltz version of the Shadwen main theme.

The 1:16 long track which is simply called "valse" (waltz) can be downloaded without the sound effects from the trailer from here:
