Astro Bunny's electro-pop treads a fine line between melancholy and euphoria. Even the pair’s more uptempo songs are infused with a sense of sadness, thanks in part to vocalist Lena Cha’s beautiful, plaintive voice. However, the electronic beats and pulses crafted by Nu infuse the thoughtful lyricism with a sense of brightness and electricity. Nuanced and emotive, these ethereal songs are lively enough for the start of a night out while still giving off soothing, dreamy vibes to lull you to sleep at the end of it.
