"First in a series," said Demmel. "After Marta and I had so much fun doing 'No Excuses', I invited my buds Dave McClain (Sacred Reich/Machine Head), Richie Faulkner (Judas Preist), Mike Inez (Alice in Chains, Ozzy, BLS, pretty much every band) and resident Bad-Ass Lzzy Hale (Halestorm) to jam on one of my favorite tunes by one of my favorite bands Mixed by Paul Fig, Vid edit by Todd Shuss. More 'Collab-A-Jams' coming and look for a guest-oriented Guitar breakdown and play-through show coming as soon as the Shelter in Place rules allow."
