For me, music is, among the many other things it is to me, a way to creatively channel the difficult emotions into something creative, with the possibility of working through them to a positive outcome... so, here are a couple "darker" pieces of mine... BTW, I love the sound of an organ at full blast! These are older pieces.
Cruelty, Martyrdom, and Transcendence:
In the Lion's Mouth:
Anger and Surrender:
Symphony No. 1 mv 3 "Nigredo"
