Question: Which person on the Angel of Retribution album is gay?
Context: "Judas Rising" is a song by heavy metal band Judas Priest.  It is the opening track on the band's 2005 album Angel of Retribution.  The song is about the Judas Priest "Messiah" on the cover of the albums "Sad Wings of Destiny", "Painkiller" and "Angel of Retribution".  .  It was also included on the album's The Essential Judas Priest and The gay liberation movement of the late 1960s through the mid-1980s urged lesbians and gay men to engage in radical direct action, and to counter societal shame with gay pride.  In the feminist spirit of the personal being political, the most basic form of activism was an emphasis on coming out to family, friends and colleagues, and living life as an openly lesbian or gay person.  In this period, annual political marches through major cities, usually held in June (to commemorate the Stonewall uprising) were still known as "Gay Liberation" marches.  It wasn't until later in the seventies (in urban gay centers) and well into the eighties in smaller communities, that the marches began to be called "gay pride parades."  The movement involved the lesbian, gay, bisexual, and transgender community in North America, South America, Western Europe, and Australia and New Zealand. Oscar San Juan Martinez is a fictional character from the US mockumentary-style television series "The Office" played by Cuban actor Oscar Nunez.  Martinez was one of the few openly gay characters in broadcast television at the time that the series aired.  Nunez, who is straight, did not know his character might be gay when he first signed on.  For the 2006–2007 season, Gay & Lesbian Alliance Against Defamation (GLAAD) reported he was the only LGBT (lesbian, gay, bisexual, transgender) person of color character on a regular series.  For the 2007–2008 season he was the "only remaining gay character on a half-hour comedy program" and the only LGBT lead or supporting character who is a person of color.  For the 2009–2010 season, Martinez was one of four people of color LGBT regular series characters; in 2010–2011 there were six and in 2011–2012 there were five. The Night Angel Trilogy is a fantasy series written by Brent Weeks.  The story follows the life of Azoth (later Kylar Stern) as he struggles as a guild rat to become the ultimate wetboy (an assassin with magical talent, such as the ability to muffle sound or to block an attack), but then tries to leave it all behind and finally becomes the avatar of retribution: the Night Angel. The Retribution Tour was a 2005 concert tour by British heavy metal band Judas Priest which was in support of the album "Angel of Retribution".  It ran from 23 February 2005 until 3 December 2005. A gay skinhead, also known as a gayskin or queerskin, is a gay person who identifies with the skinhead subculture, sometimes (though not necessarily) out of sexual interest.  Some gay skinheads have a sexual fetish for skinhead clothing styles.  Some are attracted to skinheads' outward displays of masculinity.  Gay skinheads figure in the work of gay artists such as Canadian painter Attila Richard Lukacs and filmmaker Bruce LaBruce.  Gay skinheads have been featured on the catwalks of fashion designers Alexander McQueen and Jean-Paul Gaultier since the early 1990s. Retribution Gospel Choir is the eponymous debut album from Low singer-songwriter-guitarist Alan Sparhawk's band Retribution Gospel Choir.  The album was released in the US on March 18, 2008, through Mark Kozelek's Caldo Verde Records.  Kozelek also produced the album. Robert John Arthur Halford (born 25 August 1951) is an English singer and songwriter, who is best known as the lead vocalist for the Grammy Award-winning heavy metal band Judas Priest and famed for his powerful wide-ranging voice.  AllMusic says of Halford: "There have been few vocalists in the history of heavy metal whose singing style has been as influential and instantly recognizable", possessing a voice which is "able to effortlessly alternate between a throaty growl and an ear-splitting falsetto".  Halford was voted number 33 in the greatest voices in rock by Planet Rock listeners in 2009.  In addition to his work with Judas Priest, he has been involved with several side projects, including Fight, 2wo and Halford.  In 1998, he came out as gay in an interview with MTV News. Gabâ or gabaa, for the people in many parts of the Philippines particularly among Visayans, is the concept of a non-human and non-divine, imminent retribution.  A sort of negative karma, it is generally seen as an evil effect on a person because of their wrongdoings or transgressions.  The word has later been recycled for translating "divine retribution" or "divine fury" in the translations of the Bible to many local dialects in the Philippines.  It is also translated as nemesis.  The opposite of "Gaba" is "Grasya", literally "Grace" in Spanish, which pertains to "blessings from the Heavens". Angel of Retribution is the fifteenth studio album by British heavy metal band Judas Priest, released in 2005.  It is the band's first album since "Painkiller" (1990) to feature Rob Halford.  The album debuted at #13 on the US "Billboard" chart, which made it the third highest chart of a Judas Priest album (the second being "Nostradamus" and the highest being "Redeemer of Souls").  The album was produced by Roy Z, who co-wrote the song "Deal with the Devil".
