This song is simply called 'Underworld'. I envisioned it as a hell theme in a video game.
It uses the wonderful Mai Tai synth from Studio One 3, as well as the (now free) Firebird synth. The string sections are from the Sonatina Symphonic Orchestra (http://sso.mattiaswestlund.net/) Sound font.
Artwork was drawn by myself in Aseperite.
