An electro-dance diva in another incarnation, Boston-based vocalist/guitarist Erin Harpe’s precocious vocals mesh well with the blues, imbuing this set with a most appealing personality without overtaking her obvious flair for the roots.  Small-group backup is highlighted by the solid journeyman harmonica play of Richard Rosenblatt. The teasingly tasty title track stands out, as do “Good Luck Baby”, “Future Blues” and Lucille Bogan’s “M&O Blues”.
