The male contestants went head-to-head on American Idol 2013 during Hollywood Week. Many were cut during the sudden death a capella round, where each singer performed a snippet of a song for the judges and were swiftly given verdict. We then got into the group performance round, which had an interesting twist.

Instead of letting the contestants choose their own groups, the producers handpicked which singers would be performing together, leading to some interesting personality clashes. Some, like The Math Heads, passed with flying colors. But quite a few, like Country Queen and Oz, suffered from a lack of team mentality.
