Tip! ** Edition of 100, glass-mastered CD, includes poster ** A new face from the furthest North-East of Italy, Trieste: the city of the "bora", a powerful and relentless wind that for many of its inhabitants represents a state of mind, more than a simple typical atmospheric event. Petroglifi Solubili is the project by Loris Zecchin (Solar Ipse fanzine), born in 2021 with a simple sampler (the legendary Roland SP-404) and gradually expanded with an equipment that includes a number of synths, guitar effect pedals, and contact microphones.

"Segnale unico di avvio" is the sixth release after five CD-Rs, always privately edited and available only in physical format. The first source of inspiration was the Merzbow pre-laptop era and the furious and darting cut-ups of Killer Bug. Cascades of loops, sudden bursts of noise to eat the sound spectrum with its tongues of fire and more meditative decompression interludes.  Seven tracks composed in almost full social retreat in his own home, obtained by arranging the equipment on the kitchen table and always favoring an approach to composition as intuitive and primordial as possible. Inseparable from the sound part is the "skin" of the album, the artwork, composed of the collages made in the same period as the compositions.

Meticulously mastered by Jack Callahan, "Segnale unico di avvio" is a record that marks a new point in today's noise music maps.
