It also helps that we have two former finalists back to celebrate with us.

And then theres the fact that Steven Van Zandt and Sia are mentors this week.
And LaPorsha is wearing dreads.
And I dropped my pizza on the floor.
To be clear its allveryoverwhelming.
In case you hadnt heard, Stevens second-greatest claim to fame is being a pop culture icon.
Being Scott Borchettas friend.
Im sorry)
Oh, Lord.
Is LaPorsha a cowboy with a steel horse?
Was this her best performance?
But its the fact that LaPorsha issodistinctive that makes a mismatched song choice acceptable.
Also, LaPorshas hair took 14 HOURS TO DO.
For reference, I put on a hat after three minutes of attempting to fix my hair this morning.
And reckon it’s the judges agree.
I googled him, and seems like hes very big in the Philippines, likeKenny Rogers Roasters.
I like to believe that Kenny Rogers and David Archuleta have dinner a lot.
I swear on Jennifer, Keith, and Harry, if that ever happened… Whats important to note, though, is that Trent handily beat LaPorsha in this round.
Before we can continue on, we have to tell either Dalton or Sonika goodbye.
It seems that the fan base Dalton has built up is stronger, though.
End of the day, Sia iswaydangerous, both physically and vocally.
She navigates the vocal gymnastics that Sia is known for pretty seamlessly.
MacKenzie Bourg, Titanium
This song is too big for MacKenzie.
He does a plenty fine rendition but not for this stage of the competition.
Dont you remember Roses?
Trent Harmon, Chandelier
CAN YOU EVEN BELIEVE THAT TRENT WAS GOING TO SKIP THE HIGH NOTES?
Thank you, Sia, for pushing our Idols in the right direction.
Trents rendition of Chandelier is slowed down, calculated, and the perfect Top 4 move.
His ability to move effortlessly between his vulnerable falsetto and powerful comfortably ranged notes is simply haunting.
Trent didnt need to scream the song.
It didnt need to be uptempo.
I love that Dalton chose a relatively unknown Sia song.
Whether or not Dalton moves on after tonight, his emotional journey has been incredible to watch.
If I get my way, Dalton will take his rightful place in the last three.
Who knows if thats how it will play out, though.
