King Gizzard & the Lizard Wizard are an Australian rock band formed in 2010 in Melbourne, Victoria. To call them "rock" feels limiting, that's just what their wikipedia says, and they don't have a description of themselves anywhere I can find.
I guess they more psychedelic than anything else, but my favorite song is There is no planet B, which isn't.
