Following Beyoncé's work on "1+1" is like a journey to the center of her craft, a stripping away of every distraction until all that's left is her voice. Without it, "1+1" would be a muted ballad: Its simple guitar line and stardust-sprinkled strings serve no purpose other than to evoke a sense of familiar romantic intimacy, and then to elegantly step aside while Beyoncé delivers one of her most wonderfully impassioned performances ever.
"1+1" possesses that slightly scary intensity that has been R&B's worst-kept secret weapon since Whitney Houston's "I Have Nothing", but it also demonstrates perfectly how Beyoncé stands apart from every other big-chested diva getting her Whitney on. She lets the song sing through her with a clarity that is never clinical, a strength that never sabotages, and an expressiveness that is precisely as sentimental as its subject matter requires. Beyoncé is R&B's field marshal, demanding of her listeners and herself an absolute fidelity to the music's emotional possibilities, with a perfectly modulated vehemence that is as captivating as it is tyrannical. "Pull me in close and don't let me go," she commands, but here it's her own grasp that is thrillingly assured. --Tim Finney
