Awesome thread idea! My week:
AKALA
A rapper from the UK, so I guess he falls under the catergory of "Grime", anyway most of his lyrics are somewhat political, but in an interesting way, also his flow is the best I've heard in a long time.
DIANOGAH
Straight from Sidewinder is an indie rock group that at times sound more like noise or post rock.
SPANK ROCK
Another hip-hop group I should've gotten into a long time ago. They have a technoey feel to them as well.
I also got my first adolescents album, but I figure everyone knows them already.
