Millar said she was inspired by The Weeknd, Major Lazer and MØ and upon release, said; “I listen to a lot of R&B and their lyrics are quite full on.

I wanted to make her far more powerful and assertive.”[2] Millar promoted the EP with 'The Tremble Tour' across Australia throughout March and April.

'Tremble' boasts beats and synths that make the track feel full and complement the depth of Nicole's voice.

Starting off smooth and ultra sultry, it kicks up the tempo quickly, adding a power and playfulness that sees Nicole take you on a journey from beginning to end.

"[4] AAA Backstage gave the EP 3 out of 5, particularly complimenting the tracks "Tremble" and "Cover Me".
