The term "sound system" is also used to refer to a
free party sound system, also known as a
rig. The equipment includes a van,
loudspeakers,
amplifiers,
turntable decks and cables. Larger rigs might also have a
fog machine,
stage lighting,
video projectors and an
electrical generator; the generator enables the sound system to be set up anywhere. A sound system collective is usually five or more people, with larger sound systems having more members. Equipment is owned by some and others are DJs,
record producers or enthusiastic ravers who help out. They will be the people who organise
free parties and
teknivals and will be a group of friends with similar interests. Some owners purposely use second hand equipment, to reduce their risk if the equipment is stolen or damaged. This type of rig is called a "suicide rig" and usually used at insecure locations where it may get stolen or damaged and if it is suspected that police will have knowledge of the party. Sometimes a sound system collective is well known for its wide travels. This type of collective can be described as modern
nomad tribes or
new age travellers. In this context the word sound system is used interchangeably to describe either the group of people or the equipment. The techno travelling scene of the 1990s was made of sound system crews like Bedlam sound system and
Spiral Tribe. The free party community has been criticized for the unkempt appearance of attendees to such events, accusations of
substance abuse of illegal drugs such as
MDMA,
ketamine,
amphetamines and
LSD, and complaints about messes left behind by such parties have given the scene a negative reputation. However, despite such complaints, the scene continues to grow with a large following in
Bristol,
Abergavenny,
Newport,
London,
Devon and
Cornwall. ==See also==
