Jon Brooks is a busy man.
Apart from his excellent output as the Advisory Circle he also has a few even more esoteric releases available through bandcamp under his own name, and runs an excellent blog : cafekaput.blogspot.com
My favorite of his Jon Brooks material is Music For Thomas Carnacki, written as a companion to William Hope Hodgson's Carnacki The Ghost Finder stories. Creepy evocative stuff.
You can ( and should ) listen to or buy Music For Thomas Carnacki below :
