Even a day before Coachella, the hype train still has not come to a full and complete stop.

Announced on Facebook today, What So Not will be playing a surprise set tomorrow at the Polo Fields. And seeing as there’s a convenient slot closing out the Do Lab stage tomorrow, we’re inclined to think that’s where he’s gonna be.

It’s been over a year since Flume left What So Not, leaving Emoh Instead by his lonesome, but we should be expecting new music from WSN if Emoh is to be believed on his post; some special guests are apparently showing up, too.

We won’t rule out the possibility that he’s playing somewhere else tomorrow, but our money is on the Do Lab stage – 11:45pm.
