"American Idol" will air its first remotely produced finale in its 18-season history at 8 p.m. Sunday on ABC, with two Los Angeles-area singers among the Top Seven.
The two-hour broadcast will begin with the revealing of the vote reducing the field to five.
The Top Five will each then perform two songs. The first will celebrate their induction into the Top 5, and the second will be a previously performed song and their new "American Idol" single.
