Silent Spring is a collaboration between Tim Coster (head of CLaudia), Shannon O'Brien, and Joshua Rutter. Their three-inch CD-R release consists of one thirteen minute improvised track that manages to cover a lot of sonic ground. The piece opens with some soft electronic pings and tones, then lightly plucked guitar. A series of high and low frequency drones create a backdrop as the sound suddenly builds in sound an intensity. As the track moves along, mechanical tones, ranging from feedback-style buzzes to old-school synth-esque tones, rise and fall in the foreground. This is punctuated by abstract female hums and vocalizations that weave in and out of the mix throughout.

Taken together, the abstract sounds of the performers combine into a quality piece of meditative improvisation. Simply put, there is a lot going on in the thirteen minutes of the piece, and as a result, it never grows tedious or dull. It's a small, but mighty slab of sound. 8/10 -- Matt Blackall (4 March, 2009)
