Here's 16-year-old Allison Iraheta, former winner of a Telemundo singing competition.
She sings "Alone" by Heart -- really one of the most overdone songs on AI. It starts off a little rough, but eventually enters full powerhouse mode in the chorus. It's obvious this girl can really rock out. She hits the high notes...and then some. Very compelling stage presence, too. The performance is very reminiscent of an early Kelly Clarkson.
Randy: "You just blew it out the box right there."
Kara: "You don't even know how good you are."
Paula: "I think you could sing the telephone book."
Simon: "You're the best tonight by a clear mile. It's like the competition just started right now."
