A1 MOOK

A1 Mook opens his YouTube channel, @A1mook, on April 25, 2021. His earliest uploads — "Could be," "Crank that remix," "Stop it," "Trollin," and "Coffin FREESTYLE REMIX," all from 2021 — carry the geo-tag "BOSTON," as do later uploads, including a promotional "Boston Worldstar" account that reshares his material. That platform tag, repeated consistently, is the only documented basis for his tie to the city: there's no first-person hometown statement, and no specific neighborhood identified beyond "Boston" generally. His releases, from the start, carry the label credit "NdaSkope Ent," consistent across Apple Music and Shazam.

On January 23, 2022 he releases SEED OF 6, his debut album: nine tracks — Late Night, Run Up, Die Young, Eater, What You Want, Street Talk, Murda, Never Cared, and Recap, Pt. 2 — confirmed on Spotify.

On April 18, 2023 comes Held Dangerous, his sophomore album: thirteen tracks, with the same count confirmed on both Spotify and Apple Music. That same year he releases the singles "Trollin" and "Stop it," both on February 9, 2023.

On January 16, 2024 he appears as a guest on "Don't Gotta Lie," a BadNewzz single — his first confirmed collaboration credit. Late that year he keeps a steady pace of his own singles: "A1 Mook (extra disrespectful)" (November 17), "Brotherly Love" (November 25), and "Betta Chill" (December 10). The pace continues through 2025: "Cold hearted" and "Funny to me" (both January 9), "Play Ball" (January 16), "My life" (April 22), and "A1 Flow" (August 22).

On February 7, 2026 he releases the single "Lit In The Bity," and on February 23 comes Toxic love, his most recent EP: four tracks — Toxic love, Cruising, Multiple personalities, and Roses And Rain — confirmed identically on Spotify, Apple Music, and Shazam. That same year documents a two-way collaboration with Yalla2x_: he appears as a guest on "Souls" (February 25, 2026) and on "Free Drilla," the third track of Yalla2x_'s EP Lost In The Lights (July 30, 2026).
