Caroline Esmeralda van der Leeuw (born 26 April 1981), known for the music project Caro Emerald, and latterly The Jordan is a Dutch pop and jazz singer who mainly performs in English.

The debut Caro Emerald album, Deleted Scenes from the Cutting Room Floor, was released on 29 January 2010.

[3] Caroline Esmeralda van der Leeuw was born on 26 April 1981, in Amsterdam, the Netherlands[4] to a Dutch father and an Aruban mother.

She started singing lessons at age 12 with James Gilloffo in Amsterdam and joined a girl vocal group, Les Elles, under his guidance.

The song, "Back It Up", had been written by Schreurs and Canadian songwriter Vince Degiorgio and was based around a hip-hop beat created by Robin Veldman and Jan van Wieringen.

[9] The demo then reached public notice around the world online and radio stations started playing the song.

Writing began in the summer of 2008 using the mix of "Back It Up", 1940s to 1950s jazz, easy listening, orchestral Latin, combined with infectious beats as a model.

[9] Adopting a sample based approach but with live instrumentation, the writing sessions drew from a wide range of influences including jazz organist Jackie Davis, exotica composer Martin Denny, mambo king Perez Prado, 1920s to 1930s jazz, and van der Leeuw's own vocal inspirations of The Andrews Sisters, Billie Holiday and Sarah Vaughan.

[9] Their usual method would be for Schreurs to create the ideas and backing tracks, and then get together with top line writer and lyricist Degiorgio to write the songs.

The song gained airplay and popularity overnight and listed in the Dutch Top 40 for 12 weeks, peaking at No.

[10] Emerald's debut album, Deleted Scenes from the Cutting Room Floor, was released on 28 January 2010 in The Netherlands by Grandmono.

[citation needed] In 2011, Deleted Scenes from the Cutting Room Floor was released throughout Europe with great commercial success.

Selected credits include The Playboy Club, a brand campaign by Martini, 2 Days in New York, The Secret Circle, Wind Mobile, Strictly Come Dancing, Dancing with the Stars, The Vampire Diaries, Agent Carter, Nestlé, Ferrero Rocher, Wrigley and Disney Nature film Chimpanzee.
