Most of us place the true legends of vocal jazz (Ella, Lena, Billie, etc.) firmly in the past. But Patricia Barber, with her deep alto and delicate touch on the ivory, is a contender for becoming a 21st century great. Barber is the daughter of a Glen Miller Band sideman who came up playing jazz joints in Chicago, and today, she has 12 albums to her name as singer, pianist and bandleader. On “New Year’s Eve Song,” from her 2008 “The Cole Porter Mix,” she crafts a velvet soundscape of swelling guitars, gliding bass and her ever present vibrato-ing voice.
