Lizzy McAlpine has created a masterpiece. Her second full-length project, “five seconds flat,” is a concept album complemented by a short film, with each song laid out in chronological order. Accompanied by collaborators Jacob Collier, FINNEAS and Ben Kessler, McAlpine’s unflinchingly honest writing creates a safe space for listeners within layers of thoughtful production. The project is an intentional departure from her debut, which she says embodied a more innocent and naive version of herself — someone she’s outgrown. Instead, “five seconds flat” is a vivid representation of McAlpine’s most formative experiences in love and loss, offering fans a more mature and nuanced perspective as she navigates their aftermath.
