There’s an instructive comparison to be made between the title of Let’s Eat Grandma’s third album and that of their debut. Released in 2016, the latter was called I, Gemini, which seemed to fit perfectly. The two 16-year-old schoolfriends who made it liked to present themselves like twins, or even aspects of the same person. They wore matching outfits and makeup. On stage, they occasionally performed with their long hair obscuring their faces so you couldn’t tell one from the other. Filled with songs ostensibly concerning mushrooms, fairytales and various childhood terrors, I, Gemini really seemed to be an album about the peculiarly intense friendships that develop among teens. With its unorthodox song structures, sudden diversions into rapping and abundance of instruments played in a way that suggested the duo prized exploration over virtuosity, it sounded like a spiffed-up version of something two talented and imaginative kids might tape together over long hours in a bedroom. With its impenetrable in-jokes expressed through lyrical non-sequiturs, listening to it sometimes felt like eavesdropping on a secret society of two. Their debut single Deep Six Textbook opened with the sound of Rosa Walton and Jenny Hollingworth playing a complex clapping game.
