In terms of total, synesthetic impact, few contemporary concert experiences match the sheer intensity of a Crystal Castles show. Indeed, one might have to reach as far back as Andy Warhol’s Exploding Plastic Inevitable to find an appropriate analogue to the sensory overload inflicted by the Toronto electro-punks’ bombastic sonic assault and dizzying, strobe-lit visual spectacle.

If you’re missing Crystal Castles’ sold out show tomorrow night at 9:30 Club, never fear. Sweetlife Festival announced its full lineup this morning, and the Torontonian duo will be there. So will Girl Talk. And Lupe Fiasco.

On Friday night at 9:30 Club, a lucky thousand got to experience a very particular form of aural and visual brutality. The HARD Tour pairs a denominator-heavy ratio of musical talent with pummeling beats and bass in an attempt to offer a logical depository for teen angst, hallucinogenic drugs, and rave nostalgia. If you are curious or confused about what exactly constitutes heavy electronic music, or if you wonder which kinds of music might scare even the most reasonable parents into unplugging their children from the Internet permanently, the HARD Tour would be a pretty good jumping-off point.
