Music video
A music video to accompany the release of "Sonnentanz (Sun Don't Shine)" was first released onto YouTube on 15 July 2013 at a total length of three minutes and fifty-one seconds. It has received over 22 million views as of March 2016.

Parts of the video were filmed at the roof of the Ibis Wien Mariahilf hotel in Vienna, overlooking the 15th district.

Critical reception
Robert Copsey of Digital Spy gave the song a positive review stating:

"It's no secret that the freshest and most exciting dance tracks often take their time escaping the cliquey hub of Europe's party islands before they are set free and allowed to migrate over to the UK. The latest to wash up on our shores? Austrian duo Klangkarussell, whose track 'Sonnentanz' became a fave across the Balearics in its instrumental form last year. Naturally, it's been compacted into a more radio-friendly length and had lyrics laid over the top courtesy of 21-year-old newbie Will Heard, who also provides the impressively on-trend tortured soul vocal. Thankfully, none of this takes away from the wonderfully hypnotic production that provides a gentle comedown from summer we so sorely need."
