Jazz pianist and singer Freddy Cole happens to be the brother of the late Nat King Cole, and he built his own career at the same time that Nat, who died at age 45 in 1965, became an international star. Freddy, meanwhile, built a reputation as a prolific force in the jazz world. The New York Times has called him “the most maturely expressive male jazz singer of his generation, if not the best alive,” an assessment echoed by DownBeat, which named him “our greatest living jazz singer.” In the past two decades alone, he’s released 20 albums, including the 2010 Grammy-nominated “Freddy Cole Sings Mr. B.” In a two-night Valentine’s Day special, Freddy appears at Jazz at Lincoln Center’s Dizzy’s Club Coca-Cola, 10 Columbus Circle, Broadway at 60th St., fifth fl. Feb. 13, 7:30 p.m. & 10 p.m.; Feb. 14, 6:30 p.m. & 9 p.m. Tickets are $140 at jazz.org, and include a four-course meal with one wine pairing per person. The 10 p.m. set on Feb. 13 also offers a non-dining admission at $45.
