Rihanna's performance last night at the Brit awards with Klaxons made for interesting pairing, but the rest fell short. Is she incapable of a little improvisation on the melody, good lord. Monotony!

The whole electro-rock vibe was cool, but they could have done so much more with it. Again with that boring melody. I would have preferred to hear more Klaxons that were being drowned out by her vocals.

She performed with Mark Ronson, Adele and Daniel Merriweather.

The girl could use some critiquing from the American Idol judging crew, cause she's a little "pitchy" in her performance. Actually, Paula would never notice such a thing.
