Damn, ninjas.
Anyway, yeah, you can't lose with Biffy Clyro.
Mon da Biff!
Some other good ones:
Mumford and Sons
Joy Division
Flobots, for you more hip-hop/rap-rock needs
Daft Punk
Nirvana
And of course, Dubstep. Lots and lots of dubstep. For specific artists, I'd go with Borgore or Skream. Definitely two of the best dubstep artists out there.
