When Danny Deutsch opened Rochester's roots-rock Mecca, Abilene, he should have consulted the third little pig — you know, the one who stymied the big bad wolf by using brick — in preparation for Nashvegas powerhouse singer-songwriter Sarah Potenza. She's gonna huff and puff and level the joint. This dame is a Howitzer of a singer who croons sultry and smooth, mixed with a bluesy gutbucket grit as if she swallowed Janis Joplin. She blew them away on "The Voice," and she'll hand you your head as well. Am I gonna miss this show? Not by the hair of my chinny chin chin.
