Justice, the French electronic music duo.
The vast majority of stuff I listen to falls within two camps: 'prog/rock/metal', and 'classical'. But I've been listening to Justice since around 2008 pretty heavily (despite their having only two studio and one live album!) and they're not really much like anything else I'm into. I mean, I love Daft Punk's Discovery as much as the next person but I'd say Justice are in my top 15/20 artists. I think what I love the most about them is their percussion/rhythms/drums/groove and I seem to be more into the drums in most of the stuff I listen to than any other instrument (I'm always stopping people mid-conversation to tell them to listen to this fill or whatever), possibly because they're where the time signatures live, and I love a good groove... and Justice have that in spades.
