The solo on “Snowbound” is the kind of Baker moment you wait for. It is fragile threads of luminous melody, discovered by a series of existential choices so slow they sometimes almost stop. “Snowbound” was written by Clarence Kehner and his partner, Russell Faith, and first appeared as the title song of a 1962 Sarah Vaughn album; it was reprised in 2001 on Barbra Streisand’s Christmas Memories album.
