Question: What was Judas Priest's seventh album and produced by Gull Records?

full_context: Document 1: Hero, Hero: Hero, Hero is a compilation album of early Judas Priest recordings, released in between "British Steel" (1980) and "Point of Entry" (1981) by Gull Records.
Document 2: Stained Class: Stained Class is the fourth album by British heavy metal group Judas Priest, released in February 1978. It is the first of three albums to feature drummer Les Binks. It gained notoriety for its dark lyrics and themes, as well as 1990 civil action trial where the band were accused of backmasking that led to the suicide attempts of two teenagers. Stained Class was ranked as the greatest Judas Priest album on Stereogum.com, and was described by Steve Huey on Allmusic.com as “Judas Priest’s greatest achievement.”
Document 3: California Metal: California Metal, the first of five compilation albums released by Regency Records in the late eighties, was designed primarily to showcase the talents of the numerous unsigned Christian metal bands that had arrived on the scene following the success of Stryper. "California Metal" was quickly followed by "California Metal Volume II" (1988), "East Coast Metal" (1988), "Underground Metal" (1989) and "Underground Metal 2" (1989). As a bonus, another album released by Regency along the preceding metal line was "Classic Metal" (1990). As far as the title ""California Metal"" implies, all of the artists participating on the project come from the state of music in question and bring a variety of metal styles ranging from classic metal, melodic metal, speed metal and commercial hard rock to it. What makes "California Metal" such a noteworthy release, nevertheless, is the fact it introduced several bands that in time would become household names in the growing Christian rock, hard rock and metal music communities: "Gardian" (soon to correctly rename itself as "Guardian"), Deliverance and Neon Cross. Other artists participating on the project include Barren Cross (who debuted the previous year with its Star Song release "Rock For The King") and Mastedon which is the studio project of former Kansas vocalist John Elefante and his brother Dino. Hero was the only band appearing on the album not to go on and make a name for itself.
Document 4: Exciter (song): "Exciter" is a song by British heavy metal band Judas Priest, from their 1978 album "Stained Class". It is the opening track and is an early example of speed metal.
Document 5: Beyond the Realms of Death: "Beyond The Realms of Death" is a power ballad by British heavy metal band Judas Priest from their 1978 album, "Stained Class". Vocalist Rob Halford's performance is considered one of his finest ever, and the guitar work is noted as well, especially the solos. Many reviewers have called it one of the best songs on the album. The song is considered a Judas Priest classic, with versions of the song appearing on the albums "Priest, Live and Rare", "'98 Live Meltdown", "Live in London", "", "Live Insurrection" and many of the group's compilation albums. Drummer Les Binks has his only songwriting credit with the band for the song's main riff.
Document 6: Rocka Rolla: Rocka Rolla is the debut studio album by British heavy metal band Judas Priest, released on 6 September 1974 by Gull Records. It was produced by Rodger Bain, who had made a name for himself as the producer of Black Sabbath's first three albums. It is the only album to feature drummer John Hinch.
Document 7: Pumping Iron &amp; Sweating Steel: Pumping Iron & Sweating Steel: The Best of the Iron City Houserockers is a compilation album by the Iron City Houserockers. Released in 1992 under Rhino Records, it was at that time the only Iron City Houserockers material available on compact disc ("Love's So Tough" and "Have a Good Time but Get out Alive!" would not be reissued on CD for another seven years after this compilation appeared). The disc covers all four of the Iron City Houserockers albums from the late seventies and early eighties and places them in chronological order with a few extra tracks thrown in to make it a worthy buy for collectors. Tracks 1–5 were taken from "Love's So Tough", with "School Days", a Chuck Berry cover, being an unreleased outtake from that album. Tracks 6–11 were taken from "Have a Good Time but Get out Alive!", but with the single edit version of "Junior's Bar". Tracks 12–15 were taken from "Blood on the Bricks", tracks 16–17 from "Cracking Under Pressure" and "Goodbye Steeltown", a Joe Grushecky single released in August 1984 (after the band had broken up), was included as the final song. The songs were remastered for compact disc by Bill Inglot.
Document 8: &quot;Heroes&quot; (David Bowie song): "Heroes" is a song recorded by the English musician David Bowie, written by Brian Eno and Bowie. Produced by Bowie and Tony Visconti, it was recorded in July and August 1977, and released on 23 September 1977. A product of Bowie's "Berlin" period, the track was not a huge hit in the UK or US at the time, but has gone on to become one of Bowie's signature songs. In January 2016, following Bowie's death, the song reached a new peak of number 12 in the UK Singles Chart. "Heroes" has been cited as Bowie's second-most covered song after "Rebel Rebel".
Document 9: Metal Works '73–'93: Metal Works is a compilation album by Judas Priest, released in 1993. A remastered edition was released in 2001, with the same track listing. All material was previously available. All albums to that date are represented with the exception of their debut, "Rocka Rolla", although a live version of "Victim of Changes" (from "Unleashed in the East", with what appears to be an American sounding audience dubbed on at the end, instead of the familiar Japanese one from the album version) is used rather than the studio version on "Sad Wings of Destiny". This is because the band no longer owns the rights to their first two albums.
Document 10: Victim of Changes (album): Victim of Changes is ex-Judas Priest singer Al Atkins's fourth release, named after a Judas Priest song of the same name originally featured on the "Sad Wings of Destiny" album.

Like several others in the past, Genocide was released under the label Gull, in an effort to "capitalize on Judas Priest's popularity." Judas Priest's management firmly states that people should not buy these compilations, because even though it would seem like a new album on the surface, it's just a re-issue of material already recorded.
Document 13: The Best of Judas Priest: The Best of Judas Priest is a collection of a few select songs from Judas Priest's first two albums, and was released under Gull, the band's former record label. It was the first of many reissues of the band's earlier material produced in an effort to "capitalize on Judas Priest's popularity" and was released without any consent from the band.
