Alon Isocianu and Superfruit (that's Scott & Mitch, two of the founding members of Pentatonix) have created an enjoyably arch confection for Imaginary Parties. 

With a series of riotously colourful outfits and art direction - all carefully coordinated – and a supporting cast of mannequin-like dancers, we're in a slightly tongue-in-cheek version of classic pop video territory.

It's those deadpan expressions, with the occasional raised eyebrow, that makes you smile. They were probably cracking up with each costume change.
