Still, Timberlake is too seasoned of an entertainer not to deliver. On Monday, he played guitar, grand piano and Rhodes piano, on top of singing and dancing duties. At 33, his dance moves are fluid but limited, and there was no doubt he worked up a serious sweat on stage. He still pops and locks smoothly, and can hit choreographed moves with an efficiency that betrays his boy-band past. While his days of dazzling solely through movement are over, the most refreshing aspect of the night was the sturdiness of his tenor and falsetto. Timberlake is no vocal knockout, but almost all of his notes Monday were pure and confident.
