Piano Man Monty Alexander Fêtes Ol’ Blue Eyes at 100

He was 17 when he had a serendipitous encounter with Frank Sinatra and Ol’ Blue Eyes’ long-time pal Jilly Rizzo. The evening changed pianist Monty Alexander’s career forever. He soon became the house pianist at New York’s famed Jilly’s Saloon and developed a unique relationship with Sinatra himself. For two nights, Alexander, joined by singer Kurt Elling, will share songs and stories in honor of Sinatra’s centennial. Jazz at Lincoln’s Rose Theater, 10 Columbus Circle, Broadway at 60th St., fifth fl. Feb. 12-13, 8 p.m. Tickets are $40.50-$130.50 at jazz.org.
