*200 copies limited edition* Black Bamboo IV continues TeZ's series of electroacoustic and acousmatic performances, centered on the live transformation of acoustic sources and field recordings. Improvisations unfold through the interplay of hybrid DIY tools, traditional folk and ethnic instruments, environmental textures, and archival audio fragments. These elements are expanded and recombined through generative filters, delays, pitch shifters, and harmonizers—woven into evolving feedback loops that blur the line between structure and chance. In this new iteration, TeZ explores an even more introspective and enigmatic soundscape, where ancestral cosmic resonances merge with industrial and experimental currents.
