Conceding not an ounce of his artistry or incomparable class to his nearly 93 years, Tony Bennett remains a master singer, his marvelous jazz-pop phrasing and interpretive prowess invigorating the Great American Songbook. His latest album, last fall’s Love Is Here To Stay, is a collaboration with Diana Krall, who has periodically sung with Bennett for two decades, and the supple Bill Charlap Trio. All shine in deliciously nuanced tribute to the genius of George and Ira Gershwin, Bennett and Krall’s vocals magically intertwining while Charlap adds exquisite support. Included is a fresh version of “Fascinating Rhythm,” first recorded by Bennett in 1949. Daughter Antonia Bennett opens.
