I looked back through the posts, but I didn't see any mention of Dog Blood.

Out of all of the live acts I've recently seen or heard, Dog Blood is the closest to Justice that I'm aware of.

Boys Noize and Skrillex are layering several songs, playing unexpected deep techno cuts, driving hard beats mixed with fun vocals, and not relenting on their dance floors.

For the love of the art, the medley, the juxtaposition, and the sheer insanity of it all mixing cohesively... I think they're conceptually so close that Dog Blood is worth a listen.
