TGC #3 is the third issue of the TETRA GAMMA CIRCULAIRE series (an unknown audio magazine), initiated in 2015 by the polymorphic production platform DE PLAYER in Rotterdam. But it is also the second Special Issue of the Experimental Publishing (XPUB) programme of the Media Design Master of the Piet Zwart Institute (are you still following?). The TGC series is famous as a magazine because it has no limits nor exact face and appears in unexpected solutions and situations. TGC #3 fits right in. Concretely, very concretely, TGC #3 is in itself a particular kind of publishing platform (some may dare say a jukebox) experimentally engineered for sonic experiments, instruments, and installations. The first edition is limited to 12 copies, and to inaugurate its launch it is distributed with works created and compiled by the XPUB students.This evening, the new issue will be demonstrated in its dynamic applications and for the festivity we flew in some other nerdy sound makers and breakers.
