[2] At the age of ten, Watson travelled to Martinique, an island in the eastern Caribbean Sea, as an exchange student, living with a family she had never met before for the express purpose of learning French.

[3] In her final year at the Royal College of Music, Watson organised a debut concert, which attracted HRH Duke and Duchess of York as well as Elle Macpherson, George Michael and others.

[3] Described as "a classically trained vocalist whose rich, sumptuous voice can soar effortlessly over music written by some of the world's all time greatest composers",[4] Watson has since performed in various public and private events in Europe, Asia, and the US, working with the Royal Philharmonic Orchestra in a number of concerts, including at Cadogan Hall.

She has performed for Children in Crisis,[2] British Red Cross[3] and The Head & Neck Cancer Research Trust of The Royal Marsden Hospital[citation needed] in London, where she also sang for the Indian charity of Magic Bus in a Gala Dinner attended by Elizabeth Hurley among others at the Park Lane Hotel.

[3] In 2008, Watson performed in the Bonachela Dance Company production Square Map of Q4 at the Queen Elizabeth Hall, singing music created by Marius de Vries (producer of the film Moulin Rouge!

Equally at home giving a classical recital in traditional surroundings or singing in a club with a couple of young non-classical musicians, Watson realised she might be able to make a record that would reflect this diversity and bring together the best of different genres.

[3][19] The programme of her self-titled debut album Summer, created by Watson herself and producer Nick Patrick, is a collection of classical, popular and world music, including pieces and arrangements of music by Ludwig van Beethoven, Antonín Dvořák, Gabriel Fauré, Geminiano Giacomelli, Benjamin Godard, Ennio Morricone, Stanley Myers, Joaquín Rodrigo, Sting, Richard Strauss and others.

Watson worked with various musicians during the recording of the album, including Pino Palladino, Richard Harvey, Nigel Hitchcock, Dominic Miller and John Parricelli.

She also had Roger Vignoles as her accompanist in Sposa son disprezzata, and Marcelo Álvarez as her duet partner in Tutta La Vita by Matteo Saggese.

[22] Watson has been able to travel extensively, performing and exploring the world, spending time in Europe, Africa, Asia, Australia, New Zealand and the Americas.
