Olive/Costa Monteiro free download
Although I haven't listened to this yet, a duo of Tim Olive and Alfredo Costa Monteiro sounds great on (virtual) paper. Each has developed his own idiosyncratic and unique take on prepared guitar, frequently ending up in noisy, gritty territory. The lovely Zeromoon label has made a free download release of the duo available here.
Here's what Costa Monteiro's website says:
The duo produces a rough, feral music with moments of surprising calm and beauty, using basic technology to blast into outer realms, dark atmospheres of varying density and great textural variety. Sharp cuts and gradual transformations carry the listener from seemingly chaotic noise to ordered spaces, pierced by shafts of light.
UPDATE: I have listened to it, and it's really good!
