Labrinth premiered the song live during the results show of the fourth live-semi final of the sixth series of Britain's Got Talent, on 9 May 2012. Maxumi Magazine commented that the track demonstrates "Labrinth's Kanye West like ability to make cracking use of samples that pay homage to their originators whilst forming the basis for inventive new tunes".Don Diablo remixed the single, due to be released as part of the digital EP, but he later revealed via his SoundCloud that the remix missed the deadline and therefore was not included on the iTunes package. This song is featured in a Windows 8 commercial.
Digitalspy.co.uk reviewed the single saying "From the gospel-inspired chorus in "Let the Sun Shine" to the hi-wired grime beats on "Earthquake", Labrinth is quickly earning himself a reputation as the chameleon of the pop world. Better yet, it appears he still has plenty more ideas tucked up his sleeve, having told us he wants to put out eight singles from his debut LP Electronic Earth. So what of release number four? The singer has tried his hand at soul, interweaving singing legend Charles Wright's melody with his own contemporary and distinctly personal lyrics. "I don't make the papers, I'm far from JLS/Ain't got the X Factor, I'm not what they expect," he admits over funk-driven guitars, before the chorus of trumpets and sparkly synths shower down. It's a suit that fits him remarkably well, though given his history, we won't allow ourselves to enjoy it too much."
Several images of the music video were posted to Labrinth's official Facebook page prior to the release of the video. The official video was released on 16 May 2012, at a total length of three minutes and thirty-two seconds. The video depicts Labrinth parodying such programmes as The Fresh Prince of Bel Air, where he brings back the rotating throne from the sitcom's opening titles, Ice Age and The Simpsons, recreating scenes from the show's opening sequences and also he is seen performing on a floor with comic book artworks covering it. The video uses the single remix of "Express Yourself", rather than the album version.
