The Unexplained Sounds Group is an experimental label run by Raffaele Pezzella (who records as Sonologyst). Eighth Tower Records, Reverse Alignment, and Zero K are its sublabels focusing on experiment and acousmatic ambient recordings. Seemingly from out of nowhere, these platforms have emerged as primary sources of underground electroacoustic and post-industrial music from various corners of the world. Particularly of note are their compilations, often focusing on a specific geographic region or set of inspirational source material.
