Caleb Johnson, a rocker from Asheville, N.C., stole the show on American Idol's "home" theme night.

The 12 remaining singers were encouraged to sing songs reminding them of home.

Caleb sang Rush's "Working Man" and delivered one of the best vocals and performances of the night.

Other highlights of the evening included a well-done cover of Blind Pilot's "Just One" by Sam Woolf and a performance of "Let's Get Loud" by Emily Piriz that drew praise from the artist who released the song -- Idol judge Jennifer Lopez.
