Christina Grimmie 1st two concerts vocal range

I had this video planned on my to-do list for a long time, I hope you like it. Some really great notes on this two concerts. I think she always doubted which one of those two was her "first" concert when being interviewed throught the years, so I did xD So in case of doubt here you have a vid for both :P

She was 16 in the 1st and just turned 17 a few days ago in the 2nd. Also she didn't had singing lessons on the first of these two. Amazing right?
