Composed and recorded in Berlin from 2008 to 2010 the music consists of four electroacoustic pieces based largely on analogue synthesizer material and one long-form swarm-like composition for multiple overdubbed saxophones. Additional sounds range from metal foil floating on ultrasonic sound-beams to mechanical clickers recorded in the abandoned radar domes at Teufelsberg. The raw materials have been extensively processed and re-constructed using analogue tape and digital methods. The five pieces shift between sharply detailed blizzards of electronic interference to passages of delicate balance, between calm and turbulence, between stasis and rapid shape-shifting, between multiple virtual spaces and non-spaces.

Thomas Ankersmit is a saxophonist, electronic musician and installation artist based in Berlin and Amsterdam, who combines abstract, intensely focused acoustic saxophone work with hyper-kinetic analogue synth and computer improvisation. He also creates installation pieces that use sound, infrasound and "modifications to the acoustic characters of spaces" that disrupt the viewer/listener's perception of the exhibition space and their presence within it. He frequently works together with New York minimalist Phill Niblock. Other recent collaborators have included Kevin Drumm and Borbetomagus.

Valerio Tricoli is a Berlin-based composer, improviser, sound installation artist, producer, sound engineer and curator bridging musique concrète and conceptual forms of sound with a radical interest in how reality, virtuality and memory relate to each other during the acoustic event. He mostly uses analogue electronic devices (reel-to-reel tape recorders, synthesizers, microphones, light effects, ultrasonic speakers). The structure of the setup is ever-changing however, seeking multiple relations between the performers, the device and the space in which the event takes place. He is one of the founders of 3/4HadBeenEliminated and the Bowindo label/collective.

The CD is mastered by Rashad Becker at Clunk, in a limited edition of 1000 copies. It is packaged in a pro-press digisleeve jacket which itself is housed in a one-tone silk screened pvc sleeve with interweaving geometric designs, with artwork by Kathryn Politis and Bill Kouligas.
