'Following the "Idol" broadcast, Beyoncé's husband, Jay-Z, posted behind-the-scenes footage of his wife singing her new emotional ballad "1+1" in her dressing room. Accompanied by a pianist and her background singers, Beyoncé simply stands in front of a vanity mirror with her head humbly held low and eyes closed as she belts her way through the lyrics while her mother, nephew, and cousin, among others, watch in awe.
Jay-Z, who actually videotaped the clip, stressed the uniqueness of the stripped-down run-through. "This is the dressing-room rehearsal for 'American Idol,'" he wrote on his Life+Times website under the pseudonym Andy WarHOV. "'NO MICROPHONE. No effects."'
I love the raw version.
Its so much better than the produced one - can't you just feel the emotion?
