JACK’s “A Kick A Knife” advances with palpable emotional intensity.

With a benevolent vocal assurance and seemingly effortless flaunting of compositional prowess comparable perhaps to the greatness of either Joanna Newsom or Big Thief, Buffalo-hailing and Brooklyn-based artist Brittany Costa shines here in her solo spotlight.

The first-rate instrumental backing is majestic at times, overpowering at others, and transformative throughout.

The song nears 6 minutes, which walks the tightrope of what some in this often impatient and distraction-filled world would be willing to give undivided attention, but music lovers should know how much better off they’d be with a top-drawer tune like this in their listening arsenal.

Costa’s auspicious debut LP Alchemical Rounds is due out next month.
