Technofactor

Technofactor is a German electronic duo from the late 1990s, made up of Daniel Büchner and Christian Müller. They worked in the trance scene, and one of their tracks that got attention was "Castelos Que Ergui." The song has a melodic, atmospheric quality that fit with progressive trance at the time.

Their catalog includes other tracks like "Encontro Você Na Internet" and "Reprise." The music tends toward layered soundscapes and steady rhythms, without much of the harder edge you might find in some techno. Büchner and Müller kept a relatively low profile as a duo, focusing on studio work rather than building a public persona.

There were occasional mentions of disagreements between them, but nothing that led to a clear split or dramatic change in their output. They just kept making music in their established style. The pair didn't chase trends aggressively, which gave their work a consistent, if niche, feel within the trance genre.
