After six years of purgatorial sway, Joel Shanahan’s Auscultation project returns with a fourth full-length of dazzling, convex electronics: IV. His signature production touches have only heightened in the interim: iridescent synths; dexterous bass; slinky networks of pads and percussion; regal, rolling fog. Icy bangers of isolation and beauty crafted over long Pacific Northwest winters of endless rain.

The album evolved fitfully, polished and shelved between bursts of inspiration and malaise. This push and pull gives the music a manic, mirror ball, mood-swing movement, tilting between reverie and regret and sweaty abandon. Seven songs of memory and mirrors, haunted by shadows of the past but dreaming of futures still liquid, and unions yet to come.
