Caleb shook the roof with his powerful performance of "Chain Of Fools." The performance had everything we have come to expect from the talented artist. The judges were blown away. Keith said the performance was "killer" and went on to add that Caleb is a "Rock and Roll Viking." "You kill the audience every single time," said Jennifer Lopez. While Harry thought Caleb's performance was good, he urged the singer to reign it back next week and choose a softer song to perform. Caleb promised to do a "soft, tender" ballad next week.
