Question: What quarterly magazine did Luis Venegas contribute to as a freelancer?
Context: Christian Witness Ministries ("CWM") is a non-denominational church affiliation founded by the former National General Secretary of the Assemblies of God in Australia 1989-1992, Philip Powell.  CWM publishes a quarterly magazine, "Contending Earnestly for The Faith" (CETF), of which Philip Powell is the editor (B. Michael Bigg assistant editor) and to which a number of authors from different backgrounds contribute, including Dave Hunt (Christian apologist), Bill Randles, Mike Gendron, Aeron Morgan, Jeffrey Whittaker, Mark Mullins, Roger Winter-Smith, and Larry DeBruyn.  CWM also runs a bookshop and conducts Bible conferences and ministry tours featuring the above speakers plus Jacob Prasch, Justin Peters and Peter Stokes.  CWM is a watchman discernment ministry. Los Dregtones was a band from El Paso, Texas, led by Cedric Bixler-Zavala (vocals/drums), Ralph Jasso (guitar) and Jimmy Hernandez (bass).  The line-up changed multiple times with Julio Venegas playing bass for a long duration while Hernandez was off at music school at the Atlanta Institute of Music in Atlanta, GA.  Other members included Luis Prieto (Percussion), Brooks Miller (trumpet), Adam Young (drums), and Andrew McCoi (drums).  In 1994, they released a demo recorded at Rosewood Studios by Mike Majors (produced by Sparta), titled "Five Song Alibi".  The style of the album was not unlike what lead singer Cedric Bixler would later perform with The Mars Volta; psychedelic rock, with hints of salsa, reggae, and occasional Led Zeppelin-esque guitar riffs, with punk rock.  The cover and insert art was drawn by Julio Venegas, which features a six armed serpent women with a third eye and long ugly hair, and a symbol on the end of its tail that would later be used by Cedric and Omar Rodríguez-López on The Mars Volta's stickers, shirts, and other merchandise.  Guitarist Ralph Jasso would later play bass briefly for The Mars Volta. Amazing Stories Quarterly was a U.S. science fiction pulp magazine published from 1928 to 1934.  It was launched by Hugo Gernsback as a companion to his "Amazing Stories", the first science fiction magazine, which had begun publishing in April 1926.  "Amazing Stories" had been successful enough for Gernsback to try a single issue of "Amazing Stories Annual" in 1927, which had sold well, and he decided to follow it up with a quarterly magazine.  The first issue of "Amazing Stories Quarterly" was dated Winter 1928 and carried a reprint of H.G. Wells' "When the Sleeper Wakes".  Gernsback's policy of running a novel in each issue was popular with his readership, though the choice of Wells' novel was less so.  Over the next five issues only one more reprint appeared: Gernsback's own novel "Ralph 124C 41+", in the Winter 1929 issue.  Gernsback went bankrupt in early 1929, and lost control of both "Amazing Stories" and "Amazing Stories Quarterly"; his assistant, T. O'Conor Sloane, took over as editor.  The magazine began to run into financial difficulties in 1932, and the schedule became irregular; the last issue was dated Fall 1934. American Heritage of Invention & Technology was a quarterly magazine dedicated to the history of technology.  It was a spinoff of "American Heritage" magazine.  It started in the summer of 1985 and there were three issues a year until 1992, when it became quarterly.  Following the Summer 2007 issue (volume 23, number 1), publication was suspended (along with "American Heritage" itself).  Publication of the magazine resumed with the Summer 2008 issue (volume 23, number 2), under the slightly changed title American Heritage's Invention & Technology.  The last issue was Winter 2011 (volume 25, number 4). The Cambrian quarterly magazine and Celtic repertory was a quarterly journal focusing on articles about Celtic history and literature.  Thomas Price (1787-1848) was one its founders.  He was a cleric and historian whose bardic name was Carnhuanawc.  He was instrumental in reviving the Eisteddfod.
