cultists! You're only going halfway with your worship of The Great Old Ones
if you're not listening to The Darkest of the Hillside Thickets!
This band of raging lunatics plays H. P. Lovecraft inspired music with a driving metalic-alternative beat. They've done the soundtrack to Spaceship Zero, and have numerous albums under their belts, including Hurts Like Hell, Cthulhuriffomania!, and Cthulhu Strikes Back (their newest). The music is deep and moody, yet oddly satirical, with song titles like Burrow Your Way To My Heart (about a girl with ringworm), and Big Robot Dinosaur (about a boy and his father who rampage about in a big robot dinosaur.
Listen! You must listen! They will invade your dreams! Bring one of their CDs to your next Campus Crusade for Cthulhu meeting, and you'll be sure to be the life of the party! And remember, he of the unpronouncable name wants you to.
