This release is a totally reworked version of "Possible Forms" previously produced as CDR in edition of 100 copies by Nova Ars Digitandi, and it's a part of "Gestaltsystem" installation. It has unique conception of everchanging soundsculpture, composed by randomly juxtaposed audio fragments of the specially designed structure. This is the best digital sound art piece we ever heard, and it should appeal to all minimal electronic music admirers. Macrostructure: the black CD includes eight tracks with metrical-tonal elements, while the white CD contains eight tracks of only noise drones. Both CDs have the same peak level (0dB), so the listener can choose the respective volume of each of the two CDs. These recordings contain ultra and sub sonic frequencies; for this reason the author advices the listener not to play the CDs at high volumes. Microstructure: all the tracks are obtained from a special combination of forty different audio fragments, previously selected and extracted from various digital sources. The minimal form of the entire work was specifically created to facilitate the listening in combined modality, establishing this way a precise relationship between sign and function. Vertical audio system: using two CD players (or CD-ROM/DVD players) in Random / Shuffle and Repeat modes, both players have to be started simultaneously. So, the two records can be played together ad libitum, generating sounds and sequences in continuous movement. Possible Forms uses sound strategies based on the calculation of auditive times and spaces in order to create a different kind of audio-logic design. In this sense this work can be intended as a device able of expanding the ordinary possibilities of domestic listening and it can be presented in the form of audio installation.
