"«e:4c are H. Vasconcelos and J. Correia, a laptop duo from Porto, Portugal, and they build skyscrapers made of heavy pre and post-processed field recordings, cable static and general software sound generation. This is usually filed under 'experimental improvised electronics' and e:4c are obvious followers of Vítor Joaquim, Paulo Raposo, @c and other renowned portuguese laptop experimentalists and composers, and they are extremely good at what they do. This is laptop electronica at its best.
'Documents' contains two long and untitled pieces, #1 and #2, with many distinct moments between the two, some lighter and some deeper. While #1 is a dark themed mass of artificial inteligence sounds, filled with glitches and static, machine crunching of binary data, supported by a low hum of drones, #2 is all light: a nostalgic and emotional piece, technologically advanced, full of spectral sounds, cymbals and processed voices like some living building struggling to reach the sky high. Keeping the analogy, #1 could be the underground section of this life-pulsating tower, with all kinds of machines feeding electrical energy into the upper floors, maintaining a constant flow of information. #2 is the visible part of this living synthetic organism, it's where it all happens, where it processes and catalogues all information gathered, like a gigantic database, building floor over floor, trying to reach the infinite. Amazing stuff.» - Pedro Leitão" (From the Test Tube's release page)
