The dark narrative underlying Halloween finds exquisite expression in doom rock. You can grok this eldritch tendency at Launchpad (618 Central SW) Friday, Oct. 30. Spirit Caravan headlines. Their oeuvre includes abysmal classics like “Kill Ugly Naked”, “No Hope Goat Farm” and “Dove-Tongued Aggressor.” Local minions of Cthulhu, Shoggoth and Burque’s atramentous lords of the metal underground, Black Maria, begin the evening’s 21+ recondite ritual. It’ll cost you $10 and your soul to get in, but don’t worry, the Old Ones are pretty decent overlords. Showtime is at 9pm.
