Escala (previously known as Scala, then eScala) is an electronic string quartet, from London, England who rose to fame when they performed on and reached the final of the second series of Britain's Got Talent on ITV1 in May 2008.

Two of the four members of Escala, Izzy Johnston and Chantal Leverton, were part of Wild, a similar five-piece classical group who were signed to EMI and released an album with the label in 2005. The four members of the group met in 2005 when they were part of the string section on an arena tour withMcFly. Three of them, Victoria Lyon, Chantal Leverton and Tasya Hodges performed with Jeff Wayne on his War of the Worlds Tour in 2006.

In the first round of the show, Escala performed a "techno version" of "Palladio" by the Welsh composer Karl Jenkins, and were put through to the semi-finals by judges Simon Cowell, Amanda Holden and Piers Morgan.At the semi-final, they performed an instrumental version of "Live And Let Die" by Paul McCartney and Wings, receiving a positive reaction from the judges, with Piers Morgan describing it as "the best performance of the week". They won the public vote to win the semi-final and secure a place in the final with nine other acts.

In the final, they once again performed "Palladio", but didn't get enough public votes to make the top three acts and the show was won by street dancerGeorge Sampson.
