The remaining 11 boy band hopefuls pull at the heartstrings as they take on iconic break up songs. We follow three new bands as they learn new songs, new harmonies and continue to build new bonds with their bandmates. Each of the bands will perform, live, before architects Emma Bunton, Nick Carter and Timbaland. They will critique their performances and select one vocalist from each band who is up for elimination. Audiences at home will then vote, live, and decide who will stay and who will go.
