Maschinenfest is a yearly, three-day underground music festival featuring industrial, power electronic, noise, and dark electronic performers. There are both independent and signed bands who are booked to play, as well as many vendors for music and related paraphernalia. Featured record labels and noteworthy companies include: Ant-Zen, Hands Productions, Pflichtkauf, Spectre Records and Ad Noiseam.

Traditionally the festival has been in October, held in a bunker deep underground Aachen, Germany. The venue has posed some problems with heat, humidity and air circulation, as well as condensation dripping on to the gear of the performers, but the atmosphere of the bunker has proved quite fitting to the genres of music played throughout the festival.
