Thighpaulsandra (Timothy Lewis) is a multi-instrumentalist musician, having participated in numerous albums by the band Coil, in particular the masterpieces that are the two volumes of "Musick to Play in the Dark" and "Astral Disaster". Massimo Pupillo, meanwhile, is best known as the bassist with Zu, an Italian jazzcore trio with whom he has produced over fifteen albums. The duo's debut album "I Leave a Silver Trail Through Blackness", released in 2017, is an imposing piece of dark ambient. The next two albums continued the meticulous exploration of sonic textures that characterized their debut. Entitled respectively "Mysterium Coniunctionis" (2018) on the Mind Travels series, and "The Descent of Inana" (2019), these albums are a continuation of Uruk's own mysterious, dark universe. This new album, the fourth for Uruk "The Great Central Sun", is an experimental music album containing just two long tracks with enigmatic names, suggesting an introspective, even mystical sound experience, where the listener seems to be invited to explore hidden or mysterious aspects of himself and the universe: "Per speculum in aenigmates" (Through a mirror, in an enigma) and "Radiating rainbows". This choice of only two tracks is a continuation of their previous compositions, where each album features only two very long tracks, between 18 and 25 minutes. "The Great Central Sun" is an album oscillating between drone and ambient, in a mysterious, hazy atmosphere evoking images of interstellar travel or mental exploration. It should be perceived as a true sensory voyage, immersing the listener in a dense and complex sound universe. These two long pieces seem eternal, taking us from another space-time, while the elaborate textures and hypnotic synthesizer sounds of Thighpaulsandra create a captivating atmosphere. The result is a work in which every detail is crafted with remarkable precision, a transcendental experience, a vision of a world beyond reality.
