2HAC Volume 19: Monstrous
It didn’t make the evening news (what are they trying to hide?) but last Wednesday, a terror arose from the depths to threaten all humankind. Tentacles, teeth, claws, fangs…it has all that, and hunger. Can 61 intrepid musicians stop this horror? Tune in to Bandcamp to find out!

I contributed a track to the latest Two-Hour Album Challenge (2HAC), "Entropy". My song is called "Gone Missing" and is about my dad, who passed away recently after struggling with dementia. This was by far the most personal, intense, draining piece of art I've
