Perf takes over B.leza to celebrate the release of Amuleto Apotropaico's second album, Língua Espúria. The label's first release was the 2025 self-titled debut. It distilled two years of concerts into four pieces where improvisation, drone and ritual momentum blurred. Língua Espúria (Spurious Tongue) speaks another language. António Feiteira moves away from the guitar-and-drums interplay that anchored the debut and embraces a fully electronic framework of fractured rhythms, concrète textures and self-generating systems built around a machine that learned his drumming. What was once shared between two performers now runs as a single restless current. Low-lit, low-lying basslines meet lush, somersaulting FM electronics in ephedrina’s latest work. Through field-recording manipulation, sound collage and glossy synthesis, Olga Matviychuk conjures a warped timeline where prowling, inharmonic synth growls intercept baroque phrasing in an expanded, multidimensional counterpoint. usof weaves rugged patterns of digital strokes, toponymic markings of amorphous, perpetually-modulating atmospheres of vaporous chimes. Co-founder of the Rotten\Fresh and surf labels and Living Room collective, João Rochinha has proven consistent in his agitation of the ambient scene, pushing the genre into exciting new configurations.
