Boston-based vocalist Amy Black delivers a consistently satisfying and soulful simmer on a set of nicely chosen covers and genre-savvy originals.  And while the covers might draw the initial attention, particularly a classically Muscle Shoals-bedecked workup of the Sam Cooke classic “Bring It On Home” or Dylan’s “Gotta Serve Somebody”, Ms. Black’s “Woman On Fire” and “Get To Me” are scorchers screaming for airplay.
