The Let It Shine bands in the semi finals have been revealed and here's one of the final four: Iron Sun.
The Top 40 boys from the auditions were split into groups of eight before taking on a challenging yet thrilling 6 minute non-stop performance with a well known musical star.
At the end of each performance, the judges decided which five boys in the groups should progress through to the live shows as a band.
Meet Iron Sun
Iron Sun (L-R) Harry Brown, Matt Knight, Alexis Gerred, Jordan Harvey and Clinton Elvis.
The members of what is now called Iron Sun performed a mega medley with Beverley Knight, singing a mash up of classic tracks including Twist and Shout and I Want To Dance with Somebody.
First through to the group was Alexis Gerred followed by Matt Knight. They were then joined by Clinton Elvis, Harry Brown and finally Jordan Harvey who had a tense wait to find out if he was through.
The boys have decided to name themselves Iron Sun and will now be wanting the public's support to make it through to the final and possibly win the show.
From last week it's been the public that decides which band stays and goes and Iron Sun are into the semi-final.
You'll be able to vote via phone or online for your favourite band and choose who should make it into the grand final.
Let it Shine's live shows continue tonight (February 18) with the semi-final at 6:55PM on BBC One. The results will air the same night at 8:45PM.
