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", 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 also been a regular performer in the Royal Households of the United Kingdom, most markedly with her performance to celebrate the 60th anniversary of the Royal Philharmonic Orchestra at Buckingham Palace.
