Common features of contemporary Techno-DNB tracks are: Half bar looped percussion, 8-bar blueprint drum sequences, dark-sh or psychedelic-like melody based on stabs or bleeps, monotonious theme based on various samples that keeps on repeating sequentially through time.
On the other hand, from the late 1990s on, a growing number of artists (Cause 4 Concern, Stakka & Skynet, Konflict and even more Kemal with his solo productions), Stratus, Gridlok, Rascal & Klone, Jarman aka Raiden, Bulletproof, Falcon (aka DJ Amir aka Tekken), also Bad Company (notably their "Digital Nation" LP), Black Sun Empire, STA, Paul B, SKC, Chris.SU, Dom & Roland, and others) produced and released many tracks in the then unclear, non-defined sub-generic field between Neurofunk and Techstep that experimented with subtle and technoid sound aesthetics, counter-dynamic and percussion-based loop constructions without the use of distorted midrange synths as lead sounds, rather using stabs and dark-ish, non-cheesy but trancey arpeggio melodies, often explicitly using Techno tracks as sources for samples and loops. These artists and their music did and does fit neither Neurofunk nor Techstep, they have rather been sometimes described as "technoid", but there had never been a proper, fitting genre name until the term "Techno-DNB" emerged in Mannheim (citation needed) in 2003. It was finally established (and explicitly accepted by the artists and labels) as the proper description of this small yet growing Drum and Bass subgenre which was more explicitly related to Schranz, having virtually abandoned melody, strings and chords as musical ingredients.
Early examples the genre first made thier way into circulation via a few pioneer labels such as Off-Key, Re-Con, Sinuous & Tilt-Recordings. As demand grew over time, more and more producers started to write Techno-DNB tracks which ultimatly led to more labels beginning to support and release them (M-Atome, Position Chrome, Freak Recordings, Leet Recordings, Subsistenz and others).
