A hallucinogen is a psychoactive agent which can cause hallucinations, perception anomalies, and other substantial subjective changes in thoughts, emotion, and consciousness.The common types of hallucinogens are psychedelics, dissociatives, or deliriants. By contrast, Stimulants, Opioids, and other psychoactive drugs are not explicitly hallucinogens because a 'hallucination' is visual terminology. The psychoactivity of opioids is devoid of visual anomalies, though the 'numbing' can be considered dissociation from pain. Hallucinations are not an uncommon symptom of amphetamine psychosis, but as they are not a primary effect of the drugs themselves, amphetamines are not considered hallucinogens. While stimulants do not induce hallucinations without abuse, the nature of stimulant psychosis is not unlike delirium.
L. E. Hollister's criteria for establishing that a drug is hallucinogenic are as follows:
Simon Posford (born 28 October 1971), better known by his stage name Hallucinogen is an English electronic musician, specializing in psychedelic trance music. His first studio album, Twisted, released in 1995, is considered one of the most influential albums in the genre. He has toured India several times.
His second album, The Lone Deranger, was released in 1997. A third album, In Dub, was released in 2002.
He is also the founder of the label Twisted Records and works in the electronic duos Younger Brother and Shpongle. Younger Brother initially began as a side project of Posford and Benji Vaughan and represented a transition away from previous projects which emphasized a more synthesized style.
Though his music has been described as "heavily driven by psychedelica", he always performs while sober due to the complexity of operating computers during his events.
ARCA or Arca may refer to:
Alejandro Ghersi, better known by his stage name Arca, is a Venezuelan record producer, consultant, mixing engineer and DJ based in Dalston, London.
Arca was born in 1990 in Caracas, Venezuela into a wealthy family. His father was an investment banker and his mother studied International Studies. His family moved to Connecticut for a time, before returning to live in a gated community, where he was privately educated and had the luxury of piano lessons. He describes his childhood as “kind of in a bubble”, and had difficulty accepting the fact that he was gay. He later attended the Clive Davis Institute of Recorded Music at NYU.
In 2012, he released three EPs on the UNO NYC label: his debut as Arca, Barón Libre,Stretch 1, and Stretch 2.
In 2013, he lent additional production on four songs from the Kanye West sixth studio album Yeezus, in which he also served as one of the three production consultants along with Hudson Mohawke and Young Chop and as a producer on FKA Twigs' EP2. He self-released the &&&&& mixtape for free, and was involved in an audio-visual performance of &&&&& alongside Jesse Kanda, who contributed the visuals, at MoMA PS1 in October 2013.
