Casey Abrams and Haley Reinhart are both in possession of raspy, smoky, husky and ultimately sexy voices -- so this duet of Carole King's 'I Feel the Earth Move' was no yin vs. yang. Their duet of one King's biggest hits was all sizzle and heat.

The performance wasn't being judged and was not up for voting, but that didn't stop Abrams and Reinhart from bringing their "A" game. Abrams scatted a little and towards the end of their duet, it was like they were trying to outdo one another. It was a bit of healthy competition within the space of a single song.

Steven Tyler called Abrams a "weird beard" and reminded him and Reinhart that these late season performances really have to matter and that their duet was everything he wanted.
