Jack Black and Kyle Gass of Tenacious D are headed to Austin with Shine America to promote Ghost Ghirls, a web comedy about 2 hilariously inept ghost hunters, coming to the Yahoo! Screen.

A watch party and concert will be presented by Yahoo! in the web company's venue at SXSW on March 13th. One of the episodes screened during the watch party features Val Kilmer.

Jack Black had this to say.

"There is no better place to unleash the beast that is Ghost Ghirls on an unsuspecting audience. Austin knows how to rock, and how to party, and how to marvel at the supernatural forces that inhabit our world. I'm so proud of this show, and I will be there with bells on, to bask in the glory."
