Annahstasia’s voice is unique. It doesn’t just sing—it expresses deep emotions, stretching and sometimes almost exploding into a smoky wail. She doesn't do fancy vocal tricks. Instead, her deep voice almost whispers to you, saying, "Feel this heartbreak with me."

Tether creates a dreamy atmosphere with the help of producers Andrew Lappin, Jason Lader, and Aaron Liao. Here, percussion is more of a feeling than a sound, with basslines supporting guitars that float like lost spirits. It's not so much about speed but about a mood of slow vulnerability.

In "Take Care of Me," delicate words and high notes balance on the edge of romantic breakdown. "Be Kind" is a lesson in dramatic silence and deep regret, where Annahstasia admits, "I… Never learned… To be kind"—each pause like a gentle yet painful revelation.

While other artists chase popular hits, Annahstasia prefers to leave a gentle impression. In "Unrest," she takes domestic life and gives it an eerie feel, reminiscent of Nick Drake’s style. "Waiting" picks up the pace slightly, using raspy runs and a Mellotron for a gentle lift. Even during the album’s livelier moments, there’s always a subtle darkness to the lyrics.

She approaches emotional uncertainty almost like a sport. "Silk and Velvet" humorously critiques the urge to compromise by making quietness a form of defiance. In the final song, "Believer," she combines gospel harmonies, electric guitar, piano, and her own doubts into a six-minute self-reflection, softly posing the question, "Can I be lonely here with you?"
