In Inertia is Jakarta-based musical collaboration of Fitrah Akbar and Annissa Utami. Formed in 2020, this duo crafts a unique sonic landscape that blends ambient, post-rock, and cinematic tones with a hint of dream pop. Known for their ethereal sound, In Inertia creates music that is light on lyrics but rich in instrumental storytelling, using processed guitar delays, airy vocals, and ambient synthesizers to immerse listeners in a serene, reflective space. In contrast to the heavier, distortion-driven tones often associated with post-rock, In Inertia introduces a softer, almost meditative touch. Their sound is designed to evoke positive memories and create a sense of calm, resonating with those seeking peace and self-acceptance through music. With each track, In Inertia draws listeners into a sweet, dreamlike experience, offering a new depth to the Indonesian music landscape that balances introspection with tranquility.
