IN: Terence Kemp McKenna (November 16, 1946 - April 3, 2000) was an American ethnobotanist, mystic, psychonaut, lecturer, author, and an advocate for the responsible use of naturally occurring psychedelic plants. He spoke and wrote about a variety of subjects, including psychedelic drugs, plant-based entheogens, shamanism, metaphysics, alchemy, language, philosophy, culture, technology, environmentalism, and the theoretical origins of human consciousness. He was called the "Timothy Leary of the '90s", "one of the leading authorities on the ontological foundations of shamanism", and the "intellectual voice of rave culture". McKenna formulated a concept about the nature of time based on fractal patterns he claimed to have discovered in the I Ching, which he called novelty theory, proposing this predicted the end of time in the year 2012.

In the early 1980s, McKenna began to speak publicly on the topic of psychedelic drugs, becoming one of the pioneers of the psychedelic movement. His main focus was on the plant-based psychedelics such as psilocybin mushrooms (which were the catalyst for his career), ayahuasca, cannabis, and the plant derivative DMT. He conducted lecture tours and workshops promoting natural psychedelics as a way to explore universal mysteries, stimulate the imagination, and re-establish a harmonious relationship with nature. Though associated with the New Age and Human Potential Movements, McKenna himself had little patience for New Age sensibilities. He repeatedly stressed the importance and primacy of the "felt presence of direct experience", as opposed to dogma. In addition to psychedelic drugs, McKenna spoke on a wide array of subjects including; shamanism; metaphysics; alchemy; language; culture; self-empowerment; environmentalism, techno-paganism; artificial intelligence; evolution; extraterrestrials; science and scientism; the Web; virtual reality (which he saw as a way to artistically communicate the experience of psychedelics); and aesthetic theory, specifically about art/visual experience as information representing the significance of hallucinatory visions experienced under the influence of psychedelics. McKenna soon became a fixture of popular counterculture with Timothy Leary once introducing him as "one of the five or six most important people on the planet" and with comedian Bill Hicks' referencing him in his stand-up act and building an entire routine around his ideas. McKenna also became a popular personality in the psychedelic rave/dance scene of the early 1990s, with frequent spoken word performances at raves and contributions to psychedelic and goa trance albums by The Shamen, Spacetime Continuum, Alien Project, Capsula, Entheogenic, Zuvuya, Shpongle, and Shakti Twins. In 1994 he appeared as a speaker at the Starwood Festival, documented in the book Tripping by Charles Hayes. McKenna published several books in the early-to-mid-1990s including: The Archaic Revival; Food of the Gods; and True Hallucinations. Hundreds of hours of McKenna's public lectures were recorded either professionally or bootlegged and have been produced on cassette tape, CD and MP3. Segments of his talks have gone on to be sampled by many musicians and DJ's. McKenna was a colleague and close friend of chaos mathematician Ralph Abraham, and author and biologist Rupert Sheldrake. He conducted several public and many private debates with them from 1982 until his death. These debates were known as trialogues and some of the discussions were later published in the books: Trialogues at the Edge of the West and The Evolutionary Mind.

IN: Jared Joseph Leto was born on December 26, 1971, in Bossier City, Louisiana, to Constance Leto (nee Metrejon). His mother has Cajun ancestry. "Leto" is the surname of his stepfather. His parents divorced when he was a child, and he and his older brother, Shannon Leto, lived with their mother and their maternal grandparents, Ruby (Russell) and William Lee Metrejon.

Leto formed the rock band Thirty Seconds to Mars in 1998 in Los Angeles, California with his brother Shannon. When the group first started, Jared Leto did not allow his position of Hollywood actor to be used in promotion of the band. Their debut album had been in the works for a couple of years, with Leto writing the majority of the songs. Their work led to a number of record labels being interested in signing Thirty Seconds to Mars, which eventually signed to Immortal Records. In 1999, Leto played a gay high school teacher who attracts the attentions of Robert Downey, Jr. in Black and White, and got a supporting role in the drama Girl, Interrupted, an adaptation of the memoir of the same name by Susanna Kaysen. He then portrayed Angel Face in Fight Club (1999), a film adaptation of Chuck Palahniuk's novel of the same name, directed by David Fincher. He began dating actress Cameron Diaz in 1999 and the couple became engaged in 2000. Leto played Paul Allen, a rival of Patrick Bateman, in the psychological thriller American Psycho (2000). Though the film polarized audiences and critics, Leto's performance was well received. The same year, he starred as heroin addict Harry Goldfarb in Requiem for a Dream, an adaptation of Hubert Selby, Jr.'s novel of the same name, directed by Darren Aronofsky and co-starring Ellen Burstyn, Jennifer Connelly, and Marlon Wayans. To prepare for his role, Leto lived on the streets of New York City and refrained from having sex for two months prior to shooting. He starved himself for months, losing 28 pounds to realistically play his heroin addict character. After the shooting of the film, Leto moved to Portugal and lived in a monastery for several months to gain weight. His performance received critical acclaim by film critics who notably praised the actor's emotional courage in portraying the character's physical and mental degradation. Peter Travers from Rolling Stone commented that Leto "excels by going beyond Harry's gaunt look to capture his grieving heart. His scenes with Ellen Burstyn as Sara, Harry's widowed mother, achieve a rare poignancy as son and mother drown in delusions." Leto next appeared in the independent film Highway. Set in 1994, Leto is caught with the wife of his employer, a Vegas thug, and flees to Seattle with his best friend Jake Gyllenhaal in the week preceding Kurt Cobain's suicide. Filming finished in early 2000, but the film was not released until March 2002 on home video formats, although originally scheduled for a theatrical release. During this period Leto focused increasingly on his music career, working with producers Bob Ezrin and Brian Virtue on his band's debut album 30 Seconds to Mars, which was released on August 27, 2002, in the United States through Immortal and Virgin. It reached number 107 on the US Billboard 200 and number one on the US Top Heatseekers. Upon its release, 30 Seconds to Mars was met with mostly positive reviews; music critic Megan O'Toole felt that the band managed to "carve out a unique niche for themselves in the rock realm." The album was a slow-burning success, and eventually sold two million copies worldwide.
