Ultralyd is an avant-garde, experimental group that hails from Norway, known for their eclectic and often abrasive approach to music. The members include Kjetil Møster on saxophone, Anders Hana on guitar, Kjetil Brandsdal on bass, and Morten J. Olsen on drums and percussion. Their work frequently ventures into the realms of noise music, free jazz, and drone, characterized by a confrontational and improvisational style that demands attention and challenges traditional musical structures.

With notable releases such as "Inertiadrome" (2010), "Conditions for a Piece of Music" (2007), and "Chromosome Gun" (2005), Ulralyd has carved out a unique niche within the experimental music scene. "Inertiadrome" epitomizes their dark and intense sonic landscapes, filled with relentless energy and a futuristic atmosphere. "Conditions for a Piece of Music", on the other hand, showcases the band's more composed side, weaving complex arrangements with spontaneous outbursts, while "Chromosome Gun" represents their rawer and more visceral early sound. Together, these works encapsulate the band's talent for creating an immersive and uncompromising auditory experience that defies easy categorization.
