“Make up your mind/I can kill or be kind,” Samantha Fish declares on “Kill or Be Kind,” the title track of her latest album. While the Kansas City native can kill you softly with such relatively restrained and soulful pleas, she is more likely to crank things up on hard-rocking songs like “Bulletproof.” And her fiery vocals are made even more searing by her uncompromising guitar playing as she tears through such rollicking tracks as “Watch It Die.” Fish initially sets her foreboding vocals to a low R&B simmer before her guitar starts raining down incendiary sparks and her singing turns to a full-on, powerful blues wail. All her pyrotechnics serve an emotional purpose, though, as her intertwined guitar solos and vocal melodies are aimed straight at the heart. With bayou blues-soul man Marc Broussard.
