What is Techno & Trance?

On Videojam, "Techno & Trance" groups the harder, hypnotic end of electronic dance music: techno's machine-driven 4/4 minimalism, melodic techno's emotive after-hours builds, and trance's euphoric peaks. Tempos typically sit 120-145 BPM, with arrangements designed for long mixing and peak-time dancefloors. The pillar is Videojam's grouping; techno, melodic techno, and trance are distinct tags in their own right.
