In March 2012, Oritsé Williams revealed that JLS had decided to work with top American producers for their fourth record, so they can give their fans a "great album".

[14] The album features collaborations with both Bebe O'Hare and Tiffany Foxx, two independent artists who are well known on the underground circuit in the United States.

[16] Shaun Kitchener of AMAZEPOP gave it a positive review, comparing it favourably to JLS's previous album Jukebox (2011).

They’re sensibly taking a step away from the half-cooked urbanised electro-pop that filled their last couple of albums; leaving the guitar-driven bubblegum choruses to One Direction and letting The Wanted get on with their own brand of club-ready ladpop."

[18] Kate Lucey of Sugarscape believed that JLS had "...upped their game for Evolution; released R&B, urban flavoured pop, and mastered it".

"[25] Writing for 4Music, Chris Younie was highly positive in his review: "We've always known [JLS] were suave and sophisticated, but this has never been more evident than on this latest album.

Regarding "Hottest Girl in the World", he said "...it was a relief to hear the group ditch their tired R&B-dance hybrids to serve up a cool slice of Justin Timberlake-styled pop.

"[20] In a review for AllMusic, Matt Collar said: "The fourth album from 2008 X Factor runner-up JLS, 2012's Evolution features more of the British boy band's slick, dance-oriented R&B.

This time, JLS have teamed up with big-name producers Mr. Bangladesh (Usher, T-Pain) and Rodney Jerkins (Michael Jackson, Justin Bieber).
