I'm not really a fan of Rihanna's but I thought she did a good job given the low energy level of the crowd. Imagine stepping onto a stage as the last act of the night around 3am and facing a crowd that acts as if they're interested at gawking at you but overall, don't sing and dance as you, a singer, perform. Wouldn't you find that a a bit daunting and a somewhat of a downer? Now, imagine stepping onstage to a crowd that's absolutely PUMPED UP about seeing you perform! They're all singing along with you, dancing their butts off, and clearly loving the music.

Which crowd would you respond to the most? Which crowd would get YOU pumped up and excited about performing because you knew that everyone there was a fan of yours and was there to see YOU, not just to finish out the concert night?

Given the response level of the crowd I'm not too surprised that her own energy level was a bit low. Rihanna herself even made reference to the crowd's lack of energy:

"Las Vegas, ya'll a little too quiet for me. Ya'll a little too quiet for my preference."
"iHeart Radio, ya'll now warming up?"
"Ya'll feel alright? Not too tired?"
"I need ya'll to turn up real quick, it's my last song."

The most energetic audience members were the girls that she let sing a couple of words to Umbrella. The FIRST audience group that is; the second group on the other side of the stage didn't even act as if they knew the words to the song (explaining why she didn't give anyone the microphone). And what was up with that woman not even dancing to the beat? I had to laugh at that.

Anyway, in my opinion, she gave a good performance under the circumstances. And even though I'm not a big fan (nothing against her, I just tend to listen to other types of music), it was clear to me that she has singing talent. I even purchased the mp3 of Only Girl!
