Walker was born in the Wimbledon district of London, England to Jamaican parents, but moved to Regensburg, Bavaria, Germany when she was four.
"[2] Walker began working on music independently providing vocals for garage artists such as 187 Lockdown and TNT.
Walker also provided vocals on the Shanks & Bigfoot album Swings and Roundabouts, most notably on the UK top 20 hit "Sing-A-Long".
[3][4] During this time, she was introduced to producers James Yarde, Sammy Jay and Amber Rene of Xosa Entertainment.
Walker travelled to LA to record some demo tracks and then returned to the UK, continuing her attempts at landing a deal.
Receiving her demos from LA, months later, Walker's UK management sent the recordings to labels in the US, who requested to see her.
In a review from the BBC, Denise Boyd stated that "In Ms Walker we have an artist who can bravely take on the US diva and who may even come out unscathed on the other side.
"[5] Upon the release of the album, Walker explained the more commercial direction by stating, "A lot of people didn't really know where to put me, I was 23 but everybody thought I was about 90 the way they were going on!".
[19] Reviews for L.O.V.E were also positive with the Daily Mirror stating that "The opening track confidently predicts that This Is My Time and, with a voice that knocks competitors into the underachieving box and songs a cut above her substandard debut, Ms T is in the ascendant.
Walker stated that "Dekkor gives creative control and freedom of expression, much better than being on a major label where you have to watch what you say."
Matilda Egere-Cooper of the BBC stated that "Its just as well that Terri Walker has returned to good form with her third LP, as the faux pas that was her second album didn't do much for her cause...
This is one heck of an album, putting Terri firmly back in the premier league of UK singers.".
[23] Matt Snow of The Guardian gave the album three stars but stated that I Am "sounds good at an intimate, low volume but increasingly thin and flat the louder you hear it.
Walker toured the album across the UK in September and October 2006 playing in Bristol, Norwich, Rotterdam, Cardiff, Liverpool, Manchester, London and Brighton.
Prior to the announcement of her fourth album, Walker had been working with producer Salaam Remi on a side-project entitled Champagne Flutes.
She confirmed to Soul Culture that she had been working with producer Ski Beatz, that it would be released on Damon Dash's BluRoc imprint and distributed via Roc-A-Fella Records.
[31] On Herel's show, it was announced that the "So Hard" single release date would be 22 February, with the Mz Walker album following on 3 May.
[32] "So Hard" was subsequently released on 5 April 2011 and Walker announced on her blog one day previous, that the album name had been changed to Walk with Me.
[33][34] Subsequently, Walker left BluRoc and the release of both the second single, "One Day Longer"[35] and parent album Walk With Me were cancelled.
In 2012, Walker teamed up with fellow soulstress Nicole Wray to form retro-soul duo Lady.
Several months after the album's release, Walker left the duo to return to her solo career, while Wray continued to perform and tour under the Lady moniker.
On 1 December 2014, it was announced that Walker's fourth solo album, her first in nine years, Entitled, would be released on 9 March 2015 and the first single would be "Bad Boy" (featuring Frisco).
