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 with McFly. 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 did not get enough public votes to make the top three acts and the show was won by street dancer George Sampson.
The four members of Escala are professional musicians who have had experience of performing in orchestras and on tour. However, with Britain's Got Talent being a competition for "undiscovered talent", their experience was said to run counter to the spirit of the show, which Escala refuted, with Izzy Johnston saying, "It's supposed to be open to everyone, professional and amateur alike."
They were also alleged to have been invited to audition for Britain's Got Talent by Simon Cowell after they supposedly played the X Factor wrap party in late 2007. However, ITV refused claims that this was unfair, stating "Escala went through the same application and audition process as everyone else. Britain's Got Talent is open to any performer be it professional or amateur, with any talent."
The members of Escala denied that they played at the X Factor wrap party, but on 18 November 2009 on This Morning with Phillip Schofield and Holly Willoughby they admitted that they played at the wrap party that one of Escala's family members had arranged. They were told it could help their career, which it did, but Izzy Johnston still claims that she had played as part of a string section backing for Michael Bublé in his appearances as a guest on the show.
The quartet changed their name from Scala to eScala during Britain's Got Talent after it was discovered that there was already a Belgian choir using the name Scala - Scala & Kolacny Brothers. They changed the name to eScala after EMI threatened to sue, despite having used the name Scala for two years. After the show they put a lower case 'e' on the beginning to eScala but have since then reverted to Escala.
On 6 June 2008 Escala performed at the first night of the nationwide Britain's Got Talent tour in London and on 8 June it was revealed that they had signed a £1.5million contract deal with Sony BMG.
