Written by Catalan composer Ferran Fages for pianist Lluïsa Espigolé following a quote by Catalan author Carles Camps Mundó — "Barely anything: deformities of silence" — this delicate work of resonance, space and suspense slowly unfolds, the score giving Espigolé choices for timing and placement as each meaningful note or combination subsides.

Recorded live at Silence Sounds in Guelph Canada, the duo of Xavier Charles on clarinet and Eric Normand on electric bass & objects eschew idiom in favor of their unique natural language on their instruments, applying patient development of truly idiosyncratic and fascinating command through a single extended work punctuated in seven diverse passages.
