What goes on in Vegas most certainly will NOT stay in Vegas here!
Watch it go down (below)!!!
And By The Grace Of God, she treats us to another delectable jam!!!
You want another shade of #PRISM? Let's take WALKING ON AIR to the TOP spot & in exchange, I'll play a NEW song you've never heard tonight!

And we guess fans spread her new tuneage fast— because she debuted By The Grace Of God, a haunting song about suffering heartache and not wanting to live, but finding the strength to pick yourself back up!
We're so happy the Roar singer has found new love, and was able to move on, making huge career strides!
Not to mention the song is beautifully sung!
