Auscultation is Madisonian-gone-Oregonian musician Joel Shanahan’s outlet for slinkier, more subliminal productions, as inaugurated on last year’s sprawling self-titled debut for 1080p Collection. His sophomore set, L’étreinte Imaginaire (which translates generally as imaginary embrace), was recorded off and on across France and Wisconsin throughout the last year, during and between various regional tours. The album’s seven selections swerve through jazzy, sunflared house (“Black Window,” “Composure Fuzz”), glimmering rhythm (“Stranded Love”), and misted, moody electronics (“Drop Off,” “Lost You In The Fog”). As with Shanahan’s work via Golden Donna and elsewhere, structures spiral and slide, textures phase in and out of focus, and a mood of heavy longing hovers in the headphones. Even so, the sense of focus and craft-sharpening here is unambiguous; these pieces are among his most plasmatic, pensive, and aerodynamic. Slow growth on a shadowed vine. The embrace may be imaginary but the touch feels real. Mastered by Alter Echo.
