Last yr’s King Gizzard & The Wizard Lizard launch Demos Vol. 3 & 4 included a hard-rock instrumental referred to as “Converge,” which is ready to seem on the band’s forthcoming album PetroDragonic Apocalypse; Or, Dawn Of Eternal Night: An Annihilation Of Planet Earth And The Beginning Of Merciless Damnation. (They just lately shared lead single “Gila Monster.”) Sunday night time at Boston Calling, King Gizz carried out “Converge” stay for the primary time, and it had advanced fairly a bit for the reason that demo. It’s greater than twice as lengthy now, and Stu Mackenzie has added lyrics. Seems like a correct heavy metallic tune. Watch footage beneath.
