The planet is in trouble. Dire trouble. But fear not: Melbourne seven-piece King Gizzard & The Lizard Wizard return to save us all, this time armed only with blast beats, an arsenal of well-oiled guitars that are locked and loaded, and a desire to melt faces clean off. Their fifteenth studio album, Infest The Rats' Nest, out Aug 16th, is by far The Gizz's hardest and heaviest album to date. How metal is it? Very Metal. Maybe even more.
