Ten paces! Fire! American Idol's Top 2 are ready to duel.

After 15 seasons, American Idol has reached its inevitable terminus. The first night of the series' two-hour sendoff left only two contestants standing, and now it's up to America to choose whom will be the last singer standing.

Dalton Rapattoni, Trent Harmon, and La'Porsha Renae took the stage on Monday night to give their last three performances. Rapattoni, however, only had to the chance to trot out one ditty before the judges sent him packing.

Renae, however, received the chance to put her pipes to the test. The season 15 powerhouse kicked off the evening with a rendition of Battles as her potential Winner's Single. Once Rapattoni was knocked out of the running, the Mississippi native took on Dionne Warwick's A House is Not a Home (Simon Fuller's choice) ahead of her performance of Rihanna's Diamonds (contestants choice).

Harmon, meanwhile, premiered Falling for his Winner's Single. Currently billed as the seasons' frontrunner, Harmon belted out Harold Melvin & the Blue Notes' If You Don't Know Me By Now (Simon Fuller's choice) before taking on Sia's Chandelier (contestant's choice).
