An amazing band.
I'm no music critic, and I struggle with electronic classifications. But I will say Justice is among my favorite bands out there. The way they can cut up a sample to be unrecognizable, yet still sound amazing is incredible. They are a pretty creative group, and prolific remixers. They also avoid the pitfalls of most electronica in that the entire albums are good, and not just a few tracks. They aren't excessive with repetition either, with the possible exception of Stress. The second album is a Base Breaker, but if you like Digitalism, you would like it as well. For a starting sample, I would recommend listening to Phantom Part 2, Genesis, Waters of Nazareth, Civilization, Canon and Audio, Video, Disco. Give them a listen, you might like them.
