The sounds found in nature can have a very slow groove. A groove embedded by silence, so slow it can almost only be felt while spending a few hours at sea, on a forest trip, in open fields... It is this groove and the "silence" of nature that inspired the Fieldtone compositions. The music is performed by an ensemble of string instruments (kanklės, acoustic guitar, electric guitar, double bass) supplemented with drums. Book of Air's series of bundled compositions exploring the parameters of sound and time begins with Fieldtone. The title refers to "roomtone," which is the "silence" recorded at a location or space when no music is played or dialogue spoken. Every room is different, and these recordings always carry their unique character. The compositions of Fieldtone are inspired by the tempo and sonic textures of specific natural locations. By embedding this silent slowness of sound found in nature into the compositions, the details of the sounds played become much more prominent. In this way the silence itself amplifies the sounds that are played, and will also amplify the room surrounding the listener.
