Question: Regeneration: Volume I & II is a compilation album that includes two covers from an American rock supergroup formed in what year?

full_context: Document 1: The David Lee Roth Band: The David Lee Roth Band was an American rock and roll band, formed in Pasadena, California in 1985 by Van Halen frontman David Lee Roth. Originally featuring a supergroup line-up of guitarist Steve Vai, bassist Billy Sheehan, and drummer Gregg Bissonette, the band released numerous popular songs and albums from the mid-1980s until the late 1990s. Other well-known musicians in the David Lee Roth Band have include guitarist Jason Becker, guitarist Steve Hunter, guitarist John 5 (guitarist), bassist Matt Bissonette drummer Ray Luzier, and keyboardist Brett Tuggle. The band's well-known songs include "Yankee Rose", "Goin' Crazy!", "Shy Boy", "Just Like Paradise", "Stand Up", "Damn Good", "A Little Ain't Enough", "She's My Machine", and "Slam Dunk!"
Document 2: Night of the Living Dead Boys: The album was released on CD in two editions, which are significantly different. The first edition, with the "glam" cover (illustrated in this article) had the original song order reshuffled, with poorly done fade-outs and fade-ins. This edition also came with a second section, a reunion show with (at least) Stiv Bators and Cheetah Chrome present, from 1987. This edition also had extensive liner notes detailing Bators' trick of singing off-mike, and claims he re-recorded the entire album in one take, from memory, while drunk and in the booth with two groupies - in other words, typical Stiv.
Document 3: Revolution Saints: Revolution Saints is an American supergroup conceptualized by Frontiers Records president Serafino Perugino, and formed by Jack Blades of Night Ranger, Damn Yankees and Shaw Blades; Deen Castronovo of Journey, Ozzy Osbourne, Bad English and Hardline; and Doug Aldrich of Whitesnake, Dio, Lion, Bad Moon Rising, Burning Rain and The Dead Daisies.
Document 4: Jim &quot;Dandy&quot; Mangrum: James Mangrum (born March 30, 1948), better known as Jim "Dandy" Mangrum, is the lead singer and frontman for the American Southern rock band Black Oak Arkansas. He is noted for his raspy voice, long hair, and wild, sexually-explicit stage antics which sometimes included miming sex with a washboard which he often uses to accompany his singing. His stage persona is credited as having been a major influence on Van Halen vocalist David Lee Roth.
Document 5: Lady (album): Lady is a compilation of songs from the band Styx's early recordings under the Wooden Nickel Records label. It is very similar to the contemporary "Best of Styx" compilation, consisting of the same tracks as that album (albeit in a different sequence) minus the song "Winner Take All", which does not appear on this album.
Document 6: 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 7: In Death Reborn: On February 11, 2014, it was confirmed that the album's production team consisted of producers include Stu Bangas, C-Lance, Leaf Dog, Panik and including Army of the Pharaohs' own Apathy amongst others, including new faces that hadn't been producing for the group beforehand. In promotion for "In Death Reborn", Vinnie Paz released "The Flawless Victory" mixtape on March 2, 2014. Reef the Lost Cauze released a collaboration album titled "Fast Way" alongside producer Emyd on March 9, 2014. Member Doap Nixon only appeared on the song "7th Ghost" but spoke out saying, how he was only featured on one song because he had a lot of personal stuff going on and stated that there will be more of him on the LP that is due to drop in November. King Syze released his fourth studio album one month before the album release on March 25 titled "Union Terminology". Apathy pushed back the release date of "Connecticut Casual" from April to June in favour of "In Death Reborn". A week before the release of "In Death Reborn", Zilla announced he was working on his fourth studio album titled "Martyr Musick" set to be released sometime June 2014. The group released their second album of the year "Heavy Lies the Crown" on 21 October 2014. Six months after In Death Reborn.
Document 8: Ted Nugent: Theodore Anthony Nugent ( ; born December 13, 1948) is an American singer-songwriter, musician and activist. Nugent initially gained fame as the lead guitarist of the Amboy Dukes, a band formed in 1963 that played psychedelic rock and hard rock. After playing with the Amboy Dukes, he embarked on a solo career.
Document 9: Damn Yankees (album): Damn Yankees was the eponymous debut album by the American hard rock supergroup Damn Yankees. It is also notable for being the album that revived the career of guitarist Ted Nugent. It went double platinum, and featured such chart topping hits as "High Enough", "Come Again", and "Coming of Age".
Document 10: Damn Yankees (band): Damn Yankees were an American rock supergroup formed in 1989, consisting of Tommy Shaw of Styx, Jack Blades of Night Ranger, Ted Nugent of The Amboy Dukes and a successful solo career, and Michael Cartellone (then an unknown drummer who would later join Lynyrd Skynyrd).
Document 11: Suburban Legends (Tim Remix): After the departure of lead singer Chris Batstone, Suburban Legends re-released their first EP, "Suburban Legends", by removing the vocal track featuring Chris, and replacing it with a vocal track of new lead singer, Tim Maurer. Suburban Legends (Tim Remix) is essentially the same album from the Orange County based ska punk band. It was first released in 2002 in Los Angeles, California by We the People Records. Its first pressing came with a green cover which was later changed to an orange cover. The green cover version is now very hard to find. The music, however, is the same on both editions. The main difference between the two versions is that the green cover edition was released by We the People Records, while the orange cover edition was self-released by the band at the end of the year. As of 2012, both versions are out of print.
Document 12: Damn Yankees (film): Damn Yankees! is a 1958 musical film made by Warner Bros. based on the 1955 Broadway musical of the same name. The story is a modern take on the Faust legend involving the New York Yankees and Washington Senators baseball teams.
Document 13: Regeneration: Volume I &amp; II: Regeneration: Volume I & II is a compilation album by the band Styx released in 2011. It consists of re-recordings of classic Styx songs, one new track entitled "Difference in the World" and two Damn Yankees covers. The album was released first as two separate EP releases, Regeneration: Volume 1 in 2010 and Regeneration: Volume 2 in 2011. The EPs were sold on every date of Styx's The Grand Illusion/Pieces of Eight tour, which began October 14, 2010 in Evansville, Indiana, and they were sold at some of their concerts since July 2010, as well as on their website. The album would be last Styx studio release with longtime producer Gary Loizzo before his passing in 2016.
Document 14: Extended Versions (Styx album): Styx - Extended Versions: The Encore Collection is a compilation of live tracks recorded by the band Styx. The album was released in 2000, but each track on the album had been released as part of Styx's 1997 double live album "Return to Paradise".
Document 15: Generations (Journey album): Generations is the twelfth studio album by the American rock band Journey. It was the band's last album with lead singer Steve Augeri and second album with drummer Deen Castronovo, confirming the line-up of 2001's "Arrival" and 2002's "Red 13" EP. The album was given away for free by the band during most of the concerts of the "Generations Tour" in 2005, and subsequently released on Sanctuary Records later the same year.
