"Deisel Guitars was the name under which Youki Noseyama (能勢山陽生, born 1967) first operated - a duo formation that preceded his long solo career as Diesel Guitar and, later, under his own name. Materialism Rock, released on Vanilla Records in 1992, is one of the project's two cassettes from this period, followed by Atom in 1993, before Noseyama continued as a solo entity running the independent noise label Good Microphone.

The sound of this era is built from reverb, analog effects, and Morley pedals - the guitar as the site of pure sonic research, processed until the instrument's identity dissolves into texture, attack, and sustained resonance. Where some noise artists of the Vanilla orbit sought maximum density, Noseyama's approach retained an oblique relationship with rock form - the title Materialism Rock not ironic but genuinely dialectical, asking what rock sounds like when stripped of everything but its material reality. A document of one of the more quietly sustained practices in the Japanoise underground."
