[4] After graduation, she started a career in advertising, singing in her spare time with amateur and semi-professional bands.
Teal's break came when she was asked to stand in for Stacey Kent at a weekend festival in Llandrindod Wells.
This led (after some determined self-promotion, in which she drew upon her advertising skills) to a three-album contract with the jazz label Candid Records.
This song attracted the attention of BBC Radio presenter Michael Parkinson, garnering significant publicity during her period with Candid Records.
Teal has toured throughout the UK and the world, with her pianist, trio, mini big band, or Hollywood Orchestra.
[11] Teal collaborated with Van Morrison on the single "Carrying a Torch" from his album Duets: Reworking the Catalogue.
On 2nd August 2024, Teal appeared as a special guest as part of BBC Proms at the Royal Albert Hall.
