“Check it out, baby!” Marc Anthony introduced several propulsive salsa selections with his English-language catchphrase at the T-Mobile Center on Saturday, October 9. The baseball slugger Salvador Perez was part of the euphoric audience of approximately 7,500. Dancing throughout the 105-minute performance was the most fun I’ve had in public in two years. While the 16-piece band was excellent, the star’s voice was the most impressive instrument. Occasional raspiness and missed notes did nothing to negate Anthony’s profound soulfulness.
