Swedish conceptual artist Leif Elggren developed this second album in his trilogy using "The Motor", a soundwork that he's built over many years from basic fragments of sound used in installations and performances, aggregated here in an expanded form as a continuous drone, harsh on the surface but complex in its layers and sonic collisions.

Multi-disciplinary artist living in Berlin, Stefan Roigk developed "Suffering For The Promised" over a 14 year period, composing this large work of acousmatic music as an atmospherically intense yet utterly fragile piece, combining concrete sounds, field recordings and devotional vocal fragments in an eclectic and highly intimate composition of great depth and detail.

Using material from solo live performances in San Francisco, Berlin, Zurich and London between 2010 and 2015, composer and sound artist Antoine Chessex developed the two compositions of this album, extracting his electroacoustic altered saxophone work and developing them into larger works that bridge extreme and psychoacoustics approaches with great sonic depth.

Recording at the GRM Studios, the French duo of Eryck Abecassis and Francisco Meirino (phroq) use unpatched modular sythesizers that they program during performance, adding a level of risk and unpredictability to their detailed and rich sonic conversation, informed by decades of research and performance that both musicians bring to this intensely interesting album.

Germany's Fragment Factory released this compilation to celebrate their 4th anniversary, with artists Joachim Montessuis, AMK, Aaron Dilloway, Philip Marshall, Krube., Michael Barthel, GX Jupitter-Larsen, Michael Muennich, Giuseppe Ielasi, Leif Elggren and Michael and Basil Esposito.

The finale for the 2012 "Extreme Rituals" concert was this performance, where each artist used a wireless EEG headset to send brainwave signals to audio engineers who transformed them into audio, as the performers sculpt sound using meditative and ecstatic trance states.

Electroacoustic composer Jocelyn Robert creates a field recording audio map of locations he's traveled to, to which he applys audio techniques equivalent to a geographer's scaling, removing, enhancing, and adding to a map, in the process creating a journey and a story.

Kai Parviainen's Enema Syringe in a 7" release recorded in 1987, 14+ minutes of raw and primitive staccato electronics edgy with a darkly disordered mental state, a stark testimony to the tenacity of his work, which continues into the 2010s.
