Trance emerged as a form of electronic dance music around 1990, with the advent of music that was essentially techno or house, but had simplified percussion, extreme repetition, and other hypnotic effects such as sustained chords and long echoes. In trance's early years (1990-1992), it wasn't always clear whether a track was just "trancey" techno (or even beat-laden "ambient" or "deep" house), or was actually an example of what would later be called simply "trance".

Example artists in this category and time period include The Shamen, Psychick Warriors Ov Gaia, The Irresistible Force, and Speedy J.
