[1] Halliday was born on 5 July 1964 in Parsons Green, London, and brought up in various locations across Europe, before eventually settling in Washington New Town, Tyne and Wear.

From 1978 to 1980, Halliday was the lead vocalist in a punk rock band named Photofitz (initially called The Incest), after which she left to start a solo career.

The first commercially released recording to feature Halliday was the single "The Smile and the Kiss" (1983) by the new wave band Bonk, on which she performed uncredited backing vocals.

The following year, Halliday's new band The Uncles released the single "What's the Use of Pretending", whereupon the singer returned to performing backing vocals for other artists, including the Robert Plant albums Shaken 'n' Stirred (1985), and Now and Zen (1988).

The following year, State of Play released an LP on Virgin Records titled Balancing the Scales, a non-hit album that spawned two singles: "Natural Colour" and "Rock-a-bye Baby".

Her album Hearts and Handshakes (produced by Halliday with Alan Moulder) was released in 1989, a year after it was finished, and four singles were taken from it: "Weekday", "Love Attraction", "Time Turns Around", and "Woman in Mind".

Dean Garcia had played on Hearts and Handshakes, and the pair now collaborated to form Curve, with Halliday serving as lead singer.

[2] In 1995, a year after the first, temporary dissolution of Curve, Halliday formed the band Scylla with Ricky Barber, Lindy Pocock, Fiona Lynsky and Julian Bown.

Scylla's only recording to have been officially released is the song "Helen's Face", which can be found on the Showgirls soundtrack of the Paul Verhoeven film of the same name.

Another Halliday track for 2013 (co-produced by Louise Dowd) called "Down In A Dark Place" can be heard in a trailer for the television series The Vampire Diaries.
