Brian McKnight Fans of 1990s R&B know that Brian McKnight is a charmer with his singing voice. But who knew that he was such a charmer in conversation? For nearly two hours on Tuesday night, McKnight charmed a roomful of women (and some of their men friends) at the soldout Dakota with his one-man concert. And that was his second show of the night. Maybe if you'd watched his now-defunct TV talk show, heard his radio show on an L.A. smooth-jazz station or witnessed him on Donald Trump's "Celebrity Apprentice" in 2009, you would have known that McKnight is a smooth talker with a quick wit. (His best line, addressed to the men in the house: "If you listen to Jay-Z when you're making love, you're not keeping her, friend.") His one-man show was autobiographical – first covering his background growing up as a self-taught piano player in a Buffalo church (he did uncanny impressions of Nat King Cole and Stevie Wonder), then performing some of his 1990s makeout music, next taking questions from the crowd (a 20-minute segment that seemed overlong) and closing by singing a few requested songs. His is a smoothly soulful, elastic voice, equal parts Luther Vandross and Stevie Wonder. McKnight, 41, sang in a high enough register that it was easy for all the women at the concert to sing along. He had them swooning to "Anytime" (with all its swoops and trills) and to the piano ballad "Back at One," his biggest hits. On "One Last Cry," he was playful to the point of being hammy. He was flirty when he brought Aisha, a fan, onstage to croon Van Morrison's "Crazy Love" to her on acoustic guitar. McKnight will perform at 7 and 9:30 p.m. Wednesday at the Dakota.
