The boundary pushing quartet from Berlin, Germany known for its intense blend of art rock, post-rock and free improvisation, extend their classic line up of two guitars, (Wilhelm Stegmeier, Eleni Ampelakiotou), bass (Roland Feinaeugle) and drums (Achim Faerber) with these guest performances and a various range of instruments from clavinet to synthesizers, creating their immersive, dense, slow-burning sound structures and mesmerizing translucent soundscapes defined by repetition, tension and constant transformation, that shift between explosive energy, structural precision and free-flowing improvisation. Physical, atmospheric, and uncompromising GLEN oscillate between minimalism and eruption. Raw yet deliberate – a controlled chaos driven by reprise, friction and gradual metamorphosis.
