The Anser, Lakoda Rayne + More Perform for Paula Abdul and Pharrell on ‘X Factor’

Paula Abdul was assigned to mentor the team of groups on 'X Factor' this season. On tonight's episode, which was supposed to air last night until Mother Nature and MLB interfered and bumped things a day, four of the eight groups Abdul is mentoring performed for her and producer Pharrell.

Abdul and Pharrell met the groups at her sprawling Santa Barbara estate. Since Abdul built her whole career on staging live acts and fashioning choreography, she was the right choice to mentor the groups. It's a lot to manage, but she can handle it! Pharrell is one of the most sought after producers in pop music, so the assist that he provided Abdul was essential.

Here's who performed and how they did:

The Anser: This SLC trio doesn't mesh with the Mormon mores of their native city, but the competition has made them brothers. The threesome turned Pink's 'F—in' Perfect' into a nearly perfect three-part harmony. There's magic in what these dudes do.

Lakoda Rayne: The judges granted these four girls who've christened themselves Lakoda Rayne a reprieve, saving them from elimination by putting them together as a "pop-country" group. They performed a twangy version of 'Born This Way,' something Lady Gaga did herself earlier this year. They meshed quickly, proving the whole is greater than the sum of its parts.

The Brewer Boys: The duo turned in a twangy version of Rihanna's 'Only Girl (In the World)' along with imperfect harmonies. They are cute, but we're not sure they were any better than the other groups that performed tonight.

4Shore: They turned in an expertly choreographed and harmonized version of 'If You Love Me' by Brownstone. The only con was that it was too polished, with Abdul and Pharrell saying the boys need to dirty up their style.
