Best friends since the age of four, multi-instrumentalists Rosa and Jenny (aged 16 and 17) create imaginative and original music that crosses the worlds of experimental pop and progressive weirdness. Every now and again we need a reminder that, as a society, we really have no business condescending to adolescents, especially with art that insults their intelligence and fails to speak to the depth of their experience. I, Gemini, the debut album by teenaged English duo Let’s Eat Grandma, inadvertently nudges us to remember that we have just as much to learn from teenagers as they supposedly do from us. “Wise beyond its years,” so to speak, the album begins with the funereal beat and keyboard swells of “Deep Six Textbook,” a song that Let's Eat Grandma enshrouded in a haze of gloom.
