Testpattern, the collaborative project of Masao Hiruma and Fumio Ichimura, emerged in Tokyo's vibrant electronic music scene of the early 1980s. Their 1982 release, "Apres-Midi," on Yen Records, became a cult synthpop classic. After the duo parted ways, Hiruma continued the Testpattern legacy by teaming up with French-American model and vocalist Evelyne Bennu. Together, they performed in Tokyo clubs and recorded throughout 1984 and 1985, producing a collection of 17 previously unreleased tracks. Their music blends lush, sophisticated electronics with minimalist production, drawing influences from Yellow Magic Orchestra and European electronic pioneers. The album "Testpattern" was released on September 19, 2025, by Dark Entries Records, featuring a fold-out poster with liner notes and lyrics.
