E

E was released in 2015 by the German label Auf Abwegen, representing a collaborative effort between the renowned experimental sound artist Asmus Tietchens and the multi-instrumentalist Okko Bekker. The work emerged from a long-standing creative dialogue between the two musicians, who have frequently intersected within the German avant-garde scene. Tietchens, known for his rigorous approach to musique concrète and synthesizer manipulation, brought a structured, abstract sensibility to the project, while Bekker contributed fluid, often surreal instrumental textures that bridge traditional composition and sonic exploration.

The album is noted for its meticulous sound design, characterized by a dense layering of processed acoustic elements and digital synthesis. The aesthetic reflects Tietchens' long-held philosophy of treating sound as an autonomous object rather than a vehicle for narrative. Upon its release, the record was well-received within industrial and ambient circles for its ability to maintain a sense of organic movement despite the mechanical nature of its production. The design of the release emphasizes the label's commitment to high-fidelity experimental works, positioning it as a significant entry in the expansive discographies of both contributors.
