Catherine Russell’s alluring voice is at once sweetly feminine as it is strong and supple. Her deep instinct for melody stems from the jazz and blues traditions that define her work. Her presence in the music world was arguably pre-ordained. She is the daughter of musicians — her father, Luis Russell, was Louis Armstrong’s longtime collaborator and musical director, and her mother, Carline Ray holds advanced musical degrees and has performed with, among many others, the great Ruth Brown. Catherine is, as the renowned jazz critic, Nat Hentoff said, “the real thing.” Seven albums and a Grammy attest to her gifts. Her newest record, “Alone Together,” is a sublime collection of songs that take on depth and nuance with her interpretive powers. Prepare to swoon.
