It is truly gritty sounding of course but the music is not and it is interesting to hear how far a person can take the concept of such a sound that is almost the lowest digital audio quality you can get and make a whole album.
It would be fun to lower the HZ to the limit,
breaking the sound up even further and see what you can get away with!
In either case it is an impressive feat and specially as it is made without any effects or modulations just pure 1 Bit samples.
The soundtrack is for free and comes with the project files.
