Kelli-Leigh (born Kelli-Leigh Henry-Davila, 15 July 1985) is a London-based producer and singer‑songwriter from Selhurst, South London. Within drum and bass and jungle contexts she works as a producer and vocalist, and her wider output spans a wide range of electronic and urban styles including house, bassline, garage and R&B.

She began in professional music as a backing and session singer. Kelli‑Leigh joined Adele’s touring band in 2011 and has performed backing vocals for Adele and for Leona Lewis. That live and studio session work led to high‑profile vocal credits: she supplied the uncredited lead vocal on two UK number‑one singles — Duke Dumont (featuring Jax Jones) "I Got U" and SecondCity's "I Wanna Feel" — and she is the credited vocalist on James Hype’s UK top‑10 single "More Than Friends".

Public documentation of Kelli‑Leigh’s producer-side methods is limited. Known facts show she operates across genres rather than from a single scene: her published activity includes singer‑songwriter releases and launching a label. In 2018 she launched her own imprint, Music Core, and released her debut solo single "Do You Wanna Be Loved Like This?". Beyond those releases, specific studio techniques or a catalogue of drum and bass/jungle releases are not widely listed in public sources.

When she appears on electronic productions her contribution is concrete: lead vocal performance, topline songwriting and session arrangement. Her voice has been used as the focal point on charting house and EDM singles (the Duke Dumont/Jax Jones and SecondCity tracks cited above) and as a credited lead on the James Hype release. Those credits demonstrate a pattern: clear, prominent vocal takes tailored for club and radio mixes, and collaboration with producers who place vocals at the centre of bass‑heavy, dancefloor tracks.

Key, verifiable connections: Adele (touring band, 2011), Leona Lewis (backing vocals), Duke Dumont (uncredited lead vocal on "I Got U"), Jax Jones (feature credit on the Duke Dumont single), SecondCity (uncredited lead vocal on "I Wanna Feel"), and James Hype (credited vocalist on "More Than Friends"). Her own label and solo single — Music Core and "Do You Wanna Be Loved Like This?" (2018) — are the primary releases tied directly to her as a lead artist.

Public biographical detail about her production catalogue in drum and bass/jungle is limited; the verifiable record is strongest for her vocal and songwriting work on charting singles, her session and touring roles, and the launch of Music Core in 2018.
