Hey there! I am an experienced composer looking to do a game jam. I did one a couple of years ago, and the soundtrack consisting of four looped tracks and a single one-shot (all of which was completed in a single working day!) can be found at my Bandcamp linked below, along with lots of other music in varying styles. Definitely at least check out the boss theme, 'Wrath of the War Chief'. I have never dabbled in sound design in a game setting, but I'm eager to learn about that, as well as the wider field of audio implementation.
Shoot me a message on Discord if you'd like to work together.
