I just released minimal_worlds_ii (https://johnoestmannmusic.com/albums/) - an album of Game Boy music made entirely with Furnace Tracker (https://github.com/tildearrow/furnace). All project files are available through the individual track pages, and all music files are Public Domain / CC0!

If you do like what you hear, worth knowing all other albums on that page are Public Domain, and all of the recent ones also have their source projects available (basically since I got really into FOSS and started structuring my projects in a way that could be easily shared)

Cheers :)
