The wild and awesome Jack Black performed a great set with Kyle Gass of Tenacious D at the soon-to-be released web comedy series, Ghost Ghirls ‘watch party’ event at SXSW last week hosted by Yahoo! and Shine America.

Another highlight of the event was the announcement that Dave Grohl will be guest starring in an episode of Ghost Ghirls alongside Jack Black and Val Kilmer.
