The two most pressing questions about Saturday's HARD Summer in downtown Los Angeles have nothing to do with quality.

With Soulwax, Crystal Castles and Major Lazer topping a bill that includes the likes of Flying Lotus and Diplo, promoter Gary Richards has assembled the kind of dance party that'll make your glowstick stand up.

But, first, will his fans forgive and forget after the 11th-hour cancellation of HARD Fest last month rendered M.I.A. missing in action?

And will everybody who does show up behave?

You figure the event will be closely monitored in the aftermath of the death of an underage attendee at the Electric Daisy Carnival a couple of months ago. So get your set times here, party hearty and party smartly.
