Vincenzo Luvineri (born October 5, 1977), better known as Vinnie Paz (formerly known as Ikon the Verbal Hologram), is an Italian American rapper and the lyricist behind the Philadelphia underground hip hop group Jedi Mind Tricks. He is also the frontman of the hip hop supergroup Army of the Pharaohs. Paz is known for his raw and gritty lyrical delivery. His lyrics frequently contain references to religion, war, politics, mythology, conspiracy theories, and the paranormal.
Paz got together members of Army of the Pharaohs to release their second album, Ritual of Battle. It was released September 21, 2007 on Babygrande Records. The album's first single was "Bloody Tears", featuring Planetary, Doap Nixon, Demoz, Vinnie Paz and was produced by DJ Kwestion. The song was based on the Castlevania tune of the same name.  On November 11, 2008, Jedi Mind Tricks released their sixth studio album, A History of Violence (album). The album sold 4,451 units in its first week out. Just like most albums, it was released on Babygrande Records. The album followed multiple summer releases from the Jedi Mind Tricks camp, including the group's first DVD, titled Divine Fire: The Story of Jedi Mind Tricks, and the Vinnie Paz-executive produced projects Jedi Mind Tricks presents Doap Nixon: Sour Diesel, Jedi Mind Tricks presents King Syze: The Labor Union, and Jedi Mind Tricks presents OuterSpace: God's Fury.  In 2010, The Unholy Terror was released. It is the third studio album by Army of the Pharaohs. The release date was March 30, 2010, but the album was released early on March 19, 2010 on UGHH.com. It was released through Babygrande Records and through Paz's own Enemy Soil.  It was during this time Paz released his debut solo album, Season of the Assassin. Many critics said the album was a step forward for Paz as an artist. "Not only has he all-but perfected his grimy braggadocio, but he also exhibits unique storytelling abilities that will make critics who dismiss him as just another hardcore rapper bite their tongues clean off." said Sean Ryon, writer of HipHopDX. It was supposed to be called Assassin's Creed but Paz changed it due to legal issues with Ubisoft. The release date for the album was on June 22, 2010. A few months later, Paz released the Prayer for the Assassin EP. The EP contained four remixed tracks from Season of the Assassin and a music video for the track Keep Movin' on. It was only available for digital download and was released on 26 October 2010.

Answer the question at the end by quoting:

Robert Dennis Crumb (; born August 30, 1943) is an American cartoonist and musician who often signs his work R. Crumb. His work displays a nostalgia for American folk culture of the late 19th and early 20th centuries, and satire of contemporary American culture. Crumb is a prolific artist and contributed to many of the seminal works of the underground comix movement in the 1960s, including being a founder of the first successful underground comix publication, Zap Comix, contributing to all 16 issues. He was additionally contributing to the East Village Other and many other publications, including a variety of one-off and anthology comics.
In January 1967 Crumb came across two friends in a bar who were about to leave for San Francisco; Crumb was interested in the work of San Francisco-based psychedelic poster artists, and on a whim asked if he could join them. There, he contributed upbeat LSD-inspired countercultural work to underground newspapers. The work was popular, and Crumb was flooded with requests, including to illustrate a full issue of Philadelphia's Yarrowstalks.  Independent publisher Don Donahue invited Crumb to make a comic book; Crumb drew up two issues of Zap Comix, and Donahue published the first in February 1968 under the publisher name Apex Novelties. Crumb had difficulty at first finding retailers who would stock it, and at first his wife took to selling the first run herself out of a baby carriage.  Crumb met cartoonist S. Clay Wilson, an art school graduate who saw himself as a rebel against middle-class American values and whose comics were violent and grotesque. Wilson's attitude inspired Crumb to give up the idea of the cartoonist-as-entertainer and to focus on comics as open, uncensored self-expression; in particular, his work soon became sexually explicit, as in the pornographic Snatch he and Wilson produced late in 1968.  The second issue of Zap appeared in June with contributions from Wilson and poster artists Victor Moscoso and Rick Griffin. In December, Donahue published the still-unreleased issue as #0 and a new third issue with Gilbert Shelton joining the roster of regulars. Zap was financially successful, and developed a market for underground comix.  Crumb was a prolific cartoonist in the late 1960s and early 1970s; at his peak point of output he produced 320 pages over two years. He produced much of his best-known work then, including his Keep on Truckin' strip, and strips featuring characters such as the bohemian Fritz the Cat, spiritual guru Mr. Natural, and oversexed African-American stereotype Angelfood McSpade. During this period, he launched a series of solo titles, including Despair, Uneeda (both published by Print Mint in 1969), Big Ass Comics, R. Crumb's Comics and Stories, Motor City Comics (all published by Rip Off Press in 1969), Home Grown Funnies (Kitchen Sink Press, 1971) and Hytone Comix (Apex Novelties, 1971), in addition to founding the pornographic anthologies Jiz and Snatch (both Apex Novelties, 1969).
