King Gizzard & The Lizard Wizard released a whopping five new albums last year. The Melbourne psych-rock outfit shared their latest LP, Fishing For Fishies, back in April, and now they’ve announced their second album of 2019. Infest The Rats’ Nest will be King Gizzard’s 15th album in the past seven years. It features two recently released heavy-hitting singles, “Self-Immolate” and “Planet B.”

Infest The Rats’ Nest sees the band embracing thrash metal. The press release says it’s their “hardest and heaviest album to date. How metal is it? Very Metal. Maybe even more.” The album was recorded with three of the seven band members. Frontman Stu Mackenzie and guitarist Joey Walker share guitar and bass duty while Michael Cavanagh handles the drums.

“The A-side of the album is set in the near future and is about real shit going on right now – especially ecological disaster,” Mackenzie explains in a statement. “We’ve got a lot of things to fear. The B-side tells the story of a group of rebels who are forced to leave Planet Earth and try to settle on Venus. I spend a lot of time thinking about the future of humanity and the future of Planet Earth. Naturally these thoughts seep into the lyrics.”
