This guys just rawk! (that is if you like electronica)
They're pretty new(created 2003, debut album in 2007)but let us hope they continue to create amazing things:
2. Mute Math
They're also pretty new (2003) but they definitely know their shit.
3. The Raconteurs
Jack White doesn't really need any more explanation, but this band (especially after seeing them live) is like the fulfillment of my dreams of good music come back. Imagine all the oldschool bands that became great. Now imagine that they actually know how to play. That's The Raconteurs.
I've changed my mind on Kanye. Instead decided to put in Audiofeels and Kate since they've got a lot of talent.
