Each of the groups then had to perform two tracks each - one current chart song and one classic track from the 1960s - in the hopes of advancing to the next round and becoming one step closer to the $200,000 prize and Sony Music recording contract.

The group are still without bandmate Ben who is attending his father's funeral. They want to stay in the competition because they owe it to him and want him to have the opportunity to experience it when he rejoins them.
- Current: 'Never Say Never' by Justin Bieber
All three judges loved the novelty factor of hearing a Justin Bieber song performed by a group of adults, with Ben joking: "I can never again say I won't enjoy Bieber sung by a bunch of Mormons!" Sara called them "charming and confident" as performers but thought they looked a little stiff.
1960s: 'The Way You Look Tonight' by Frank Sinatra
I'm swooning!" Sara joked after the performance, before praising the band for being consistently polished and theatrical but not caricatures. The panel were particularly impressed with Jake, with Shawn saying he gave the "slick, smooth, masculine, playful" vocals needed.
- Current: 'Whataya Want From Me' by Adam Lambert
The judges all thought Delilah really brought the emotion and the meaning of the song home. Kendall was namechecked for setting the tone and pace of the whole performance, while Jo was praised for her powerhouse vocals. Ben added: "This is the reason I do this gig. You're developing and innovating something and doing it with heart on TV."
1960s: 'Heatwave' by Martha and the Vandellas
Ben thought this was a challenging choice because it was hard to find something to change in the arrangement. He called the performance a bit static despite having energy, groove and fun. Sara agreed there was something missing in the arrangement but praised the group's physicality, showmanship and vocals. Shawn thought the second verse was "a bit shaky" and with four sopranos together at one point it needed something in the middle to give it more warmth.
- Current: 'Just Can't Get Enough' by Black Eyed Peas
Shawn loved the fact the group can interpret an a cappella track in a unique way, while Sara thought the arrangement was clever because it gave them all an individual moment to shine. Troy's voice was praised by all three judges, while Myke's "punk rock attitude" and theatrical stage persona was also recognised.
1960s: 'Dance To The Music' by Sly and the Family Stone
Ben and Sara both call this their favourite Urban Method performance to date, with Sara saying it drove home what a versatile group they are and Ben claiming it sounded like they were performing with a band. Shawn agreed the song "moved the way it was supposed to" and gave shout-outs to Troy and Kim.
- Current: 'American Boy' by Estelle
All three judges were fans of this performance, with Ben praising their "amazing blend and stellar arrangement". He also pointed out that Afro-Blue make jazz accessible and seem like "humble, nice people which doesn't usually go hand-in-hand with excellence". Shawn namechecked Danielle for taking control of the whole performance, while Christie's vocals were recognised by Sara.
1960s: 'Heard It Through The Grapevine' by Marvin Gaye
Ben thought some parts of the song "worked brilliantly" and they are a "soulful, executed, great group" but wondered if they overthought the track. Shawn and Sara both gave shout-outs to Trent for his vocals, while Sara said she appreciated the commitment to the choices they made which gave them a sense of unity.
- Current: 'Dynamite' by Taio Cruz
Sara praised the group for "giving every ounce of themselves" on stage although thought the groove moved around a little bit at times. She gives them props, however, for making the song sound like an actual track. Ben wanted a bit more action in the second half but praised Jamal and Danny for their contributions. Shawn called it an "overall fun" performance.
1960s: 'Can't Take My Eyes Off You' by Frankie Valli
Aaron finished the performance by singing directly to Sara and kissing her hand. "I'm blushing!" she said. "That was so sweet!" She called the group fantastic and praised their look, choreography and arrangement. Ben was a fan of the brotherhood and unity of the band, while both he and Shawn said their vocals sounded like instruments at points.
- Current: 'Price Tag' by Jessie J
All three judges thought this was an improvement on their previous performance. Ben said he'd previously thought the band was all about Moi's vocal but this time he heard the group as a whole. Shawn called it a "solid performance" with a smooth vibe but thought it needed a couple more high or low points. Sara said they didn't grab her from the get-go but it became more energetic by the middle of the song, although she advised lead singer Jenilee to be more "unabashed" with her performance.
1960s: 'Let It Be' by The Beatles
All three judges praised Moi's "emotive and expressive" vocals and the backing he was given by the group, and the fact the band turned a Beatles song into a gospel track. Ben thought it was their best performance yet but said if the group could have opened up a bit more and been less focused then it would have really "hit [him] in the chest".
It came down to Delilah and Kinfolk 9 fighting for the final spot in the next round (although Nick did not specify if this was the actual bottom two).
In the end it was Kinfolk 9 who were sent home, although the judges made a point of saying both groups had given powerful performances and this had been a hard decision for so early in the season.
Kinfolk 9 chose to give an energetic performance of 'Loser' by Beck as their swansong.
