Las Ketchup is a Spanish pop group, originally consisting of three sisters, who are best known for the 2002 song, "The Ketchup Song" (Aserejé), which sold over 7 million singles.
Las Ketchup was originally discovered by the flamenco producer, Manuel “Queco” Ruiz, who signed them to his newly formed independent Córdoba-based label Shaketown Music, which he ran together with Manuel Illán. They recorded the songs “Asereje” and “Kusha Las Payas" and shopped the demo to a number of large record companies with the intention of securing a distribution deal.
In the summer of 2002, they had a major flamenco Europop fusion hit with "Aserejé" (released as "The Ketchup Song" in the UK and other countries), which reached the top of the charts in many countries including Spain, Portugal, Colombia, UK, Italy, Greece, France, Finland, Turkey, Syria, Sweden, Norway, Belgium, Netherlands, Philippines, Switzerland, Germany, Romania, Argentina, Hungary, Poland, Venezuela, Mexico, Peru, Canada, India, Malaysia, Australia, Egypt and Puerto Rico. However, it failed to hit the Top 40 on the U.S. Billboard Hot 100.
Still worldwide, they became instant rivals to another Spanish female trio, Lunae, who released their debut single in Europe at the same time in 2003. "Aserejé" also had an accompanying dance.
In 2006, they were joined by Rocío, their fourth sister, to represent Spain in the Eurovision Song Contest 2006. The group sold over 12 million copies with the first album, but the second did not achieve the same success.
