A Duo With Phantom Contributors

A recent I Heart Lung performance is reviewed.

I Heart Lung, a guitar-and-drums duo from Southern California, makes music of calm comportment and shadowy effect. Its style combines minimalist repetition, free-jazz epiphany, noise-rock fervor and drone-music mystique: an avant-garde connoisseur’s blend, unsteadily but endlessly percolating. That may sound esoteric and precious, but I Heart Lung was neither of those things during an immersive performance at Death by Audio in Williamsburg, Brooklyn, on Tuesday night.
