Sinead Harnett

Finchley, a piano learned by ear, and a Wiley tweet

Sinéad Monica Harnett was born in London on 12 October 1989 and raised in Finchley by her mother, who had emigrated from Thailand at the age of twenty. Her Irish father lived in Australia for much of her childhood. The household listened to Etta James and Tina Turner, and when a piano arrived as a gift Harnett taught herself to play it by ear rather than by lesson.

Her first performance was a school talent show, where she sang Christina Aguilera's "Walk Away". She took ballet classes at the Royal Ballet School, then went to Arts University College Bournemouth to study acting, worked shifts in an American-themed diner and started a band called Black Tie with a friend. In 2011 the grime artist Wiley put out an open request on Twitter looking for a vocalist, found her singing on YouTube and picked her for his single — also, as it happens, titled "Walk Away". That was the door.

A decade as the guest voice

What followed was years of being the name after the comma. She sang on Disclosure's "Boiling" in 2012, contributed vocals to Rudimental's debut album and worked with the Canadian producer Ryan Hemsworth. Her own debut single, "Got Me", came out in 2013 through Black Butter Records, and the EP N.O.W. followed in 2014; its track "No Other Way" was named track of the week by The Guardian.

The comparisons were unhelpful from the start. Billboard noted the rich, soulful range and reached for Adele, but the records themselves were closer to jazz-tinged, melodic electronic pop — club-adjacent music built around a voice that did not need the club. Harnett has named Mariah Carey, Lauryn Hill, Amy Winehouse and Tina Turner as the singers she measured herself against, which says more about the intent than any genre tag does.

Three albums, and one that took two years

Lessons in Love arrived in 2019, followed by Ready Is Always Too Late in 2021. Both were well received without breaking her out of the R&B specialist bracket, and both were made while she was still finding out what a Sinéad Harnett album was supposed to sound like when nobody else's name was on the cover.

Boundaries, her third, came in April 2024 and is the record that matters. It runs to sixteen tracks and was assembled over roughly two years from something like 150 song sketches, written after a breakup sent her into therapy during a period of pandemic isolation. She has described treating the sessions as diary entries and refusing to tidy up the feeling afterwards. Her producers and co-writers included D'Mile, Camper, Tyler Reese and Jayla Darden — and Harnett has pointed out that it was the first time she had worked closely with a woman across most of a project.

The standard tracklist is deliberately free of guest verses, which for an artist who built a career on features reads as a statement; EARTHGANG, VanJess, Masego and Lucky Daye appear on the wider release. Writing about the album, Complex called it a cathartic, cleansing offering that acknowledges pain without being swallowed by it. Harnett's own framing was blunter: the album was about healing, about ending unhealthy habits and relationships, and about taking her inner child into her arms and reparenting her.

Her own imprint

Boundaries came out on Thairish Limited, Harnett's own label, in partnership with Right Hand Co. She is now based in Los Angeles, and the West Coast shows in the arrangements — more air, more space around the vocal — without the songwriting losing its close-up quality.

The independence has changed her release rhythm. "Foreign" arrived in June 2026, a sultrier, more controlled record than anything on Boundaries. "Love You" followed in August 2026 with a video directed by Adam Kudeimati, shot against a flat pink backdrop with Harnett in a black two-piece and almost nothing else in frame. The song carries the Boundaries thesis forward into something closer to instruction than confession: "I want you to love you like I do. Reframe the things that you tell yourself."

Where she stands in autumn 2026

The last two years have moved her from support billing to top billing. On 1 June 2025 she headlined the D-Railed tent at Cross The Tracks in Brockwell Park, south London, and told the crowd it was the first festival stage she had ever headlined; the reviewing consensus was that the voice carried the tent without any production help. Ezra Collective, Michael Kiwanuka and the Free Nationals headlined elsewhere on the same site.

On 25 September 2026 she played two shows in a single night at Blue Note London, an early set at 19:00 and a late one at 21:30 — a seated jazz-club format that suits the acoustic direction her live work has been drifting towards. Next comes her South African debut: The Ostrich in Cape Town on 3 October 2026, then the In The City festival at the Montecasino Outdoor Events Arena in Johannesburg on 4 October, on a bill headlined by the American rapper Isaiah Rashad. The Johannesburg gates open at midday and tickets start at R599 through Quicket. It is a first visit for both headline acts.

The box, the guitar and twenty songs

The Boundaries Tour set the template. At The Foundry in Philadelphia on 11 September 2024 the staging amounted to her name projected onto velour curtains and one oversized box as a prop — a decision the touring party made deliberately, on the grounds that each night was meant to showcase the singer and nothing else. No support act, no dancers.

The set ran to twenty songs, weighted towards Boundaries — "Thinking Less" and "The Most" among them — with older material including "Take Me Away" from Ready Is Always Too Late, an Aaliyah cover, and a mid-set acoustic stretch with guitarist Antonio Loomis that the reviewer described as tear-jerking. Across her logged setlists the recurring anchors are "If You Let Me", "Body", "Heal You", "Rather Be with You" and "Unconditional". Crowds sing the hooks back unprompted, and Harnett talks between songs about the same material the album covers — friendship, self-worth, what counts as a love worth celebrating.
