The third track is the Led Zeppelin cover, "Kashmir", and features guitarist Slash of hard rock bands Guns N' Roses and Velvet Revolver.

In 2009 Escala returned to Britain's Got Talent to perform their version of "Kashmir" un-competitively on the second live semi-final.

The eighth track is "Feeling Good", which was originally written by Anthony Newley and Leslie Bricusse for their 1965 musical The Roar of the Greasepaint—the Smell of the Crowd, but resembling the cover by the band Muse.

The tenth track is "Clubbed to Death", which was originally from Rob Dougan's debut album Furious Angels.

The Guardian newspaper in the UK stated, "a would be classical hit however the covers are endless [...] a lack of new original material".

According to media reports a cover of Snow Patrol's "Chasing Cars" was originally meant to appear on the album, but did not end up on the final release.
