The episode opens with the traditional group performance in front of judges Ben Folds, Shawn Stockman and Sara Bareilles that unites the night's remaining performing groups on the stage. This week's track is a perky, colourful rendition of 'Rhythm of Love' by Plain White Ts.
- Current: 'Edge of Glory' by Lady GaGa
Shawn admits to initially being concerned that this is a "very powerful song" that Lady GaGa "kills" with her vocals, but thinks they did a "solid, great job". Both Shawn and Sara namecheck Courtney's vocals, especially in light of her being sick. Shawn thinks Lou did his job in keeping the drive going, although Ben thinks he could have been stronger at the beginning. Sara's main advice is to work on their physicality because the performance felt a "little static".
1960s: 'You Can't Hurry Love' by The Supremes
Sara and Ben both think there are some pitch issues that come and go but think they can be rectified with experience. Shawn suggests that the song needed more midrange notes and that could have contributed to the pitch. Sara loves that Walter gave her a wink during the performance, while both she and Shawn praise Jessica's lead vocals. Ben thinks it's amazing that so many good singers can go to one school and praises the group for making the audience smile.
- Current: 'Your Love Is My Drug' by Ke$ha
All three judges love the group's "signature" sound, which they call a blend of a cappella, techno, dance and futuristic music. Ben doesn't think the "risky arrangement" worked at the top for him but he likes that they took a chance. Scott and Mitch are praised for being great and evening each other's voices out, while Sara also loves the drum and bass provided by Kevin and Avi and Kirstin's vocals.
1960s: 'Piece of My Heart' by Janis Joplin
All three judges love the unusual arrangement of the track, which they hadn't expected to witness. Shawn thinks it has a reggae feel, while Ben praises them for taking another risk, although he thinks they could have slowed down their performance at the 'come on' part of the song. Sara admits to missing the powerhouse quality of some of their other performances but likes that they have displayed their versatility.
- Current: 'Rocketeer' by Far East Movement
Sara and Ben both praise Rachael for powering through the performance despite feeling ill, with Sara telling her that her voice has "so much character, depth and texture" that it transcends anything. The judges also praise Ruby's vocals. The overall consensus from the judges is that the group is becoming more cohesive and showing growth.
1960s: 'Hold On I'm Coming' by Sam & Dave
The judges all agree that the performance kicked up a notch in the second half and they wanted that "celebration" to happen right from the start. Ben advises them to be less inhibited and more out of control, before namechecking Caleb's "insane" falsetto at the end and Ruby's efforts as his highlights. Shawn and Sara agree they are Ruby fans, and Sara also praises Isaac. In the end, she says no matter what the judges tell them, it's clear The Collective are comfortable on stage and really love what they do.
- Current: 'Lazy Song' by Bruno Mars
Sara thinks that 'Lazy Song' was the perfect choice for North Shore because its "simple, crisp, clear" style suits their own style. She thinks their personalities seem "effortless and natural" and the chemistry between them on stage is evident. Shawn agrees it was the perfect song choice and says they made it their own. Ben thinks the groove in the lead vocal was "awesome" and jokes they managed to fit in whistling "where mere mortals would have to breathe".
1960s: 'Unchained Melody' by Righteous Brothers
Ben says he heard the first pitch issues from the group in this performance but then admits that he's trying to poke holes in what was an "absolutely amazing" performance, partially because the song is from their time. Shawn, who describes the lead vocals as "silk", jokes that the pitch problems were probably because the girls in the audience were screaming so loudly the band couldn't hear what they were singing. Sara is amazed that such few voices on stage can "create such a beautiful bed of music".
- Current: 'Animal' by Neon Trees
Shawn thinks this song represents youth and energy which is what this group is, while Ben calls the energy "over the top". He thinks the song sounded like a pop song and they "rocked" the performance. Sara is also a fan of the energy and excitement and praises the cohesiveness of the group: "It was a fun, exciting performance from top to bottom so really great job."
1960s: 'Pinball Wizard' by The Who
Sara thinks it was an "awesome" rendition and feels like she's just been on Broadway. She praises frontman Michael for being a natural and loves the dynamic arrangement. She also thinks they blend their (many) voices really well. Ben thinks Pete Townsend would be proud of their arrangement and jokes it summoned Jesus Christ Superstar. He also loves the "silly" ending and praises their transitions. Shawn says Michael is a "rockstar" and although, as Ben said, there are some pitch problems it didn't take away from the performance.
- Current: 'Viva La Vida' by Coldplay
Ben calls the arrangement smart and says their voices really tapped into the song. Sara appreciates that it's been a hard transition for the band to step away from the pedals and says they have improved, although it was pitchy in parts. She thinks they might be missing another voice to fill out some parts, but thinks they did well with the voices they have. Shawn admits to being concerned about the girls' three-part harmony but they nailed it.
1960s: 'I Want You To Back' by Jackson 5
Ben thinks the interpretation of the song was interesting but isn't sure it was really effective because he wasn't moving his feet or engaged in the song. Shawn agrees that covering a classic is always dangerous because it's a classic and he thinks completely revamping the track might have been too ambitious. Sara likes it when people switch up the arrangement but thinks this could have been done differently.
North Shore and the Dartmouth Aires are the first two groups to advance to the next round of The Sing-Off, followed by Pentatonix and The Deltones.
Sonos and The Collective are the remaining two groups vying for the final place in the next round, and in the end, it is Sonos who are eliminated. They choose 'It's So Hard To Say Goodbye To Yesterday' as their swansong.
