Back for her annual October weekend at Blues Alley, the renowned Rachelle Ferrell sings a canny mix of Black musical forms. Her sound isn’t unlike some of the people for whom she used to sing backup: Lou Rawls, Patti LaBelle and George Duke. A solo star since the 1990s, she’s possessed of a flooring, more than six-octave range. Two separate sets at 8 & 10 p.m.
