The album features guest appearances from Seun Kuti, Flavour, Dyo, Jacob Banks and the London Community Gospel Choir.

While the album is described as cohesive and mature, Ohunyon noted that it plays it safe and can feel "monotonous" at times, though it still strengthens Gold's legacy.

[6] Linda Orajekwe of NotJustOk described About 30 as a deeply personal and reflective album, showcasing Adekunle Gold's growth and touching on themes like love, heartbreak, God, and family.

She praised the "great thoughtful music" and the contributions of the 79th Element band, ranking the album 10/10 and encouraging listeners to support its creative excellence.

[7] Wilfred Okiche of 360nobs found About 30 to be melodic and appealing to fans but criticized it for being "fluffy and gimmicky," with heavy reliance on guest artists to elevate its quality.

"[8] Oris Aigbokhaevbolo, writing for Music in Africa, highlighted About 30 as a showcase of Gold's transition from "loser to winner", reflecting on his improved circumstances without over-celebrating.

While the album's refined and varied sound stands out, including live band performances and collaborations with artists like Seun Kuti and Flavour, Aigbokhaevbolo noted some shortcomings in the songwriting, describing parts as lacking depth or novelty despite Adekunle Gold's growth in musicality.
