Matthias Müller / Andreas Willers: Matthias Müller / Andreas Willers

Matthias Müller and Andreas Willers craft a bold sonic adventure with their improvised soundscapes, rooted in Berlin's vibrant experimental scene. Muller wields his trombone not for traditional melodies but for sonic exploration, coaxing out breathy whispers and guttural growls. Willers answers with an electric guitar that dances between delicate, spidery lines and distorted noise. Together, they create a dynamic interplay that feels like eavesdropping on a lively conversation, full of spontaneous invention and intuitive call-and-response.

On tracks like "Geel Dropen" and "As Sik Dat Höört," Willers bends notes, uses close-handed techniques via dexterous plucking maneuvers and layered sub-vocalizations, anchored by Muller's breathy intonations and scratchy contrasts. The duo also incorporates start and stop patterns amid the trombonists' popping and slurring notes, amped by warbling phrases that abet the intensifying momentum. Their chemistry, honed over years in Berlin's jazz scene, peaks in moments like "Spökenkieker," where Muller leans into a percussive role along with multiphonics, as Willers weaves tonal threads from sparse to chaotic. These highlights highlight their knack for redefining their instruments' possibilities, drawing listeners into their creative orbit.

The album's strength lies in its moment-to-moment invention, building intricate structures from unconventional sounds. It is a journey that rewards active listening and demands focus. Think less of easy listening and more of an engaging sonic puzzle. The music avoids conventional hooks or melodies, embracing abstraction that appeals to fans of experimental music. It is like navigating a dense, intriguing forest—clear paths are rare, but the discoveries are worth it.

"Wrögelich Sungn" feels like a sketch, with Willers' microtonal chords, oddball tonalities, and muted blips that do not fully take flight. Still, these moments do not overshadow the duo's creativity. Muller and Willers react instantly to each other, sometimes finishing sonic sentences or playfully sparring through blurts and scrapes.

This album is a solid dive into free improvisation, displaying formidable technique and a fearless pursuit of unique sounds. It offers plenty of intricate and engaging moments for those who savor sonic exploration. It may not grab everyone's heart, but it is a stimulating, competent ride for adventurous ears.
