The memorials were a chance to say goodbye. The concert was meant to be more uplifting - a chance to celebrate memories of the ones who are gone and support the families left to carry on.
Like any good song, Monday night carried different meanings for everyone.
A country song on the speakers outside was a lesson from father to daughter to help families who are hurting.
"It's a tragedy what happened, so they could use all the help they can get, you've got 19 families that lost loved ones," said dad Lou Ruckstall.
The chime of the ticket scanners was a chance for a teenager to see her favorite band.
"The Band Perry, I just saw them recently, so I'm excited to see them again!" said Jessi Muha.
Jessi's laugh is a reminder for Gina Muha of how lucky she is to hug her loved one when 19 families don't get to.
"All those children who've lost their fathers, and people have lost their brothers, their uncles, their sons. It's unimaginable and I thank God that I have her," said Gina.
The snap of a guitar case was the sound of keeping a memory alive for the younger brother of fallen hotshot Wade Parker.
"Wade's little brother DJ is a huge fan of Dierks Bentley so he's so excited that he's going to be the one to continue playing this guitar for Wade since he's gone," said Wade's friend Cheyenne Wilson.
"I think the idea is to celebrate their lives and have a lot of fun, but it's a little emotional too," she said.
Six thousand tickets were sold- that's already $300,000 raised, plus there were memorial shirts for sale inside.
Dierks Bentley also presented a check for $300,000 to the United Phoenix Firefighter Charities.
