Kierin Magenta Kirby (born August 15, 1963), known professionally as Lady Miss Kier, is an American singer, songwriter and DJ.

[citation needed] Shortly after their first show in 1986, Brill was introduced to Towa Tei, a Japanese DJ of Korean descent.

Combining Kirby's vocal and writing talents with Brill's sampling skills and Tei's techno mixing, the three formed the band Deee-Lite.

[5] In 1995, after quitting the band, Lady Miss Kier moved to London where she began touring as a disc jockey and learning the technical end of production, recording, and engineering.

[1] Since going solo, she has featured and co-written with artists such as Full Cycle, George Clinton, Walter "Junie" Morrison, A Guy Called Gerald, Apollo Heights, and several P-Funk luminaries.

Outside of the studio, she showcased her live performances with new material for various music, film, and art festivals, as well as headlining several gay pride events worldwide.

[12] In 2005, motivated by the invasion of Iraq, she began internationally performing live new unreleased music, including the DFA release covering George Clinton's anti–war song "Bullet Proof".

[14] Kirby has received the following recognition in the fashion industry: In 2018, the Netflix series Big Mouth used her song "Groove Is In The Heart" for an abortion sequence.

Her words also were shared through a number of published books, including Verbal Abuse – No 3 by Chi Chi Valenti,[33] Creative Time: The Book: 33 Years of Public Art in New York by Anne Pasternak,[34] Creative License: The Law and Culture of Digital Sampling by Kembrew McLeod and Peter DiCola[35] and All Music Guide to Electronica: The Definitive Guide to Electronic Music by Vladimir Bogdanov.

In 2013, Lady Miss Kier was the featured voiceover artist in The Jazz Foundation of America's animated promo for the event "A Great Night in Harlem".

[44][45] "Groove Is in the Heart" was later licensed for use in Sega's 2008 Nintendo Wii port of Samba de Amigo, used in a section of the game where the Ulala character appears.

She supports the anti-war movement and in 2010, she released a version of the P-Funk track "Bullet Proof" with Ray Mang; she had performed it before in 2005, during her world tour.

She hosted an art exhibit at Hole Gallery in New York City and a fundraiser called "Bernin' Up NYC" to rally Sanders supporters.
