Tonight's performances tap into the canon of great number one songs throughout the generations. Only half of the remaining groups will sing their way into the judges' and audience's hearts tonight: Ten, acoUstiKats, Street Corner Renaissance and The Filharmonic. This week, Shawn individually mentored each a cappella group to help bring their acts to the next level. Together, the groups croon "In Your Eyes" by Peter Gabriel, revving up the crowd for a night of classics.
The professional background singers of Ten plan to "take everyone to church" this week with Aretha Franklin's "Chain of Fools." Shawn suggests a grittier texture be added to the vocals - people should be making the stank face! After their performance, Jewel says she wants to go to that church, while Shawn believes that was their signature performance.
"Amazed" by Lonestar was originally supposed to be a Boyz II Men track, Shawn informs the acoUstiKats, so they need to give it justice. His advice to pick a girl in the audience to sing to proves to be a successful strategy for the boys, as group member Mike wraps up the performance by proposing to his girlfriend. Regardless of the adorable proposal, Jewel praises the group on its first truly emotional piece.
The men of Street Corner Renaissance choose CeeLo Green's 2010 hit "Forget You" to showcase their talent. Shawn admires their timeless act, but cautions them to always have a beginning, middle and end to their arrangements. Many different genres work for their doo-wop sound, but Ben wants them to discover something new about themselves as people and artists.
The Filharmonic hopes to win all the girls' hearts with their own "Filipino Adam Levine." Shawn advises a heavier, dancehall beat for their interpretation of Maroon 5's "One More Night." The group seems to meet its boy band goals as the audience emits high-pitched screams before, during, and after the performance. For Shawn, it was The Filharmonic's tightest delivery yet, but Jewel wants more of the sexy anger behind the lyrics.
By the judges' marks, the bottom groups tonight are Street Corner Renaissance and The Filharmonic, forcing two extremely different styles to sing off. The attention-grabbing antics of previous sing-offs are missing from Steam's "Na Na Hey Hey Kiss Him Goodbye," as the groups politely battle. Ultimately, the judges feel The Filharmonic has more growth potential. The gentlemen of Street Corner Renaissance are sent packing.
The eight remaining groups sing their favorite #1 hits to win over the judges.
