Piece by Piece, Kelly Clarkson rips our hearts out again. Following last Thursday’s (Feb. 25) show-stopping performance of the title track of her latest studio record, the first American Idol proved exactly why she has become such an unstoppable force in the industry. With a song she wrote (with Greg Kurstin) about her father abandoning her when she was only six-years-old, Clarkson stripped away the unnecessary studio production found on the original recording and radio mix for a gut-wrenching piano accompaniment. The performance was, needless to say, one of Clarkson’s defining vocal and emotional moments of her career. The performance video, posted to Idol‘s YouTube account, has nearly 10 million views.
