Her Name Is Calla’s newest release is a fine example of the hallmark traits of the mysterious and chameleonic world of Post-Rock. While no two tracks sound the same, they are unified by the ethereal texture and atmosphere which creeps through this album. Its steady and calculated, with several layers of sound creating a chaotic resonance, but that same resonance allows for an immense scope and haunting presence. No method of music production is out of the question. Acoustic guitars, synthesizers, pianos, strings and god only knows what else take turns leading and supporting one another, keeping the listener on their toes as to what might happen next. Particularly attention grabbing are the moments when the band allows well-crafted dissonance to lurk forward in the mix, making the already mysterious sounding songs darker and more unnerving, particularly when said dissonance is birthed from what sounds like the static interference of plugging cables in and out, or attacking the string section without regard for tempo or melody. Topped off by singer Tom Morris’s mournful voice, Navigator is as unsettling as it is enchanting, and deserves a place on the shelf of any fan of post rock and experimental music.
