Belgian producer Dirk Serries, aka Vidna Obmana, is a prolific composer of deep ambient and electro-acoustic music, utilizing slow, shifting electronic figures and sparse environmental recordings to construct long, minimalist, often extremely personal textural works. Taking his nom de plume from the Yugoslavian for "optical illusion" (a concept which carries much weight in his composing, as well), Serries has released material through a wide range of different labels, including Projekt, Amplexus, Extreme, Hic Sunt Leones, Syrenia, ND, and Multimood. Born and raised in Antwerp, Serries began recording experimental noise musics in the late '80s, working solo and in combination with artists such as PBK, exploring the more abrasive side of electronic composition. Beginning with the release in 1990 of Shadowing in Sorrow, however, (the first part of what would come to be known as Vidna's ambient Trilogy) Serries began moving toward an almost isolationist ambient aesthetic, exploring themes of calm, solitude, grief, and introspection in long, moving pieces which tended to chart similar ground as American space music artists such as Robert Rich, Michael Stearns, and Steve Roach (Serries has since collaborated with both Rich and Roach). The first two movements of the Trilogy -- Sorrow, as well as its follow-up Passage in Beauty -- were self-released by Serries in 1990 and 1991, with the third volume, Ending Mirag, appearing the following year on the American ND label. The album was praised as some of the finest post-classical experimental electronic music of its time, and the Stateside connection finally opened his music up to an American audience, leading also to his association with Sam Rosenthal's Projekt label (the entire Trilogy was finally reissued by Projekt sister label Relic as a boxed set in 1996, with several new Vidna releases also appearing in the interim).
