Skrillex + Diplo + Arcade Fire = ?

What do you get when you mix everyone's indie darling with two of the biggest names in EDM? 

Reggae of course. 

Count me among the minority who thought that Arcade Fire's last album Reflektor was  great and a necessary evolution for the band. 

It looks as if this video is simply just a jam session between a bunch of cool musicians but I would love to see Win and the gang continue to broaden their spectrum musically. 

Edit: According to Win's Twitter this was in fact just a jam session.
