Question: Who did the band from the M2K Mini Tour collaborate with?

full_context: Document 1: Scorpions (band): In 2004, the band released Unbreakable, an album that was hailed by critics as a long-awaited return to form. The album was the heaviest the band had released since Face the Heat. Whether a result of poor promotion by the band's label or the long time between studio releases, Unbreakable received little airplay and did not chart. Scorpions toured extensively behind the album and played as "Special Guests" with Judas Priest during the 2005 British tour—these were the Scorpions' first dates in the UK since 1999.
Document 2: Hard rock: In the new commercial climate glam metal bands like Europe, Ratt, White Lion and Cinderella broke up, Whitesnake went on hiatus in 1991, and while many of these bands would re-unite again in the late 1990s or early 2000s, they never reached the commercial success they saw in the 1980s or early 1990s. Other bands such as Mötley Crüe and Poison saw personnel changes which impacted those bands' commercial viability during the decade. In 1995 Van Halen released Balance, a multi-platinum seller that would be the band's last with Sammy Hagar on vocals. In 1996 David Lee Roth returned briefly and his replacement, former Extreme singer Gary Cherone, was fired soon after the release of the commercially unsuccessful 1998 album Van Halen III and Van Halen would not tour or record again until 2004. Guns N' Roses' original lineup was whittled away throughout the decade. Drummer Steven Adler was fired in 1990, guitarist Izzy Stradlin left in late 1991 after recording Use Your Illusion I and II with the band. Tensions between the other band members and lead singer Axl Rose continued after the release of the 1993 covers album The Spaghetti Incident? Guitarist Slash left in 1996, followed by bassist Duff McKagan in 1997. Axl Rose, the only original member, worked with a constantly changing lineup in recording an album that would take over fifteen years to complete.
Document 3: Guns N' Roses/Metallica Stadium Tour: The Guns N' Roses/Metallica Stadium Tour was a co-headlining concert tour by American rock bands Guns N' Roses and Metallica during 1992. It took place in the middle of Guns N' Roses' "Use Your Illusion Tour," promoting their "Use Your Illusion I" & "II" albums, and between Metallica's "Wherever We May Roam Tour" and "Nowhere Else to Roam," promoting their eponymous fifth album "Metallica". The tour's opening act was Faith No More. Axl Rose had wanted Seattle rock band Nirvana to be the opening act, but frontman Kurt Cobain refused.
Document 4: Hard rock: From outside the United Kingdom and the United States, the Canadian trio Rush released three distinctively hard rock albums in 1974–75 (Rush, Fly by Night and Caress of Steel) before moving toward a more progressive sound with the 1976 album 2112. The Irish band Thin Lizzy, which had formed in the late 1960s, made their most substantial commercial breakthrough in 1976 with the hard rock album Jailbreak and their worldwide hit "The Boys Are Back in Town", which reached number 8 in the UK and number 12 in the US. Their style, consisting of two duelling guitarists often playing leads in harmony, proved itself to be a large influence on later bands. They reached their commercial, and arguably their artistic peak with Black Rose: A Rock Legend (1979). The arrival of Scorpions from Germany marked the geographical expansion of the subgenre. Australian-formed AC/DC, with a stripped back, riff heavy and abrasive style that also appealed to the punk generation, began to gain international attention from 1976, culminating in the release of their multi-platinum albums Let There Be Rock (1977) and Highway to Hell (1979). Also influenced by a punk ethos were heavy metal bands like Motörhead, while Judas Priest abandoned the remaining elements of the blues in their music, further differentiating the hard rock and heavy metal styles and helping to create the New Wave of British Heavy Metal which was pursued by bands like Iron Maiden, Saxon and Venom.
Document 5: Scorpions (band): On the Savage Amusement tour in 1988, the Scorpions became only the second Western group (not American) to play in the Soviet Union. Uriah Heep had performed in December 1987 in Leningrad. The following year the band returned to perform at the Moscow Music Peace Festival. As a result, the Scorpions developed an extended Russian fan base and still return to perform. Also in 1989, Scorpions released the compilation album Best of Rockers 'n' Ballads, which, in addition to the band's hits from 1979 to 1988, included several rare or previously unreleased tracks: "Hey You", from the Animal Magnetism sessions; the re-recorded "long version" of "Is There Anybody There?"; and a cover of The Who's "I Can't Explain", which was also included on that same year's Stairway to Heaven/Highway to Hell charity compilation album. This is the Scorpions' only compilation album to be certified platinum in the United States.Wishing to distance themselves from the Savage Amusement style, the band separated from their long-time producer and "Sixth Scorpion", Dieter Dierks, replacing him with Keith Olsen when they returned to the studio in 1990. Crazy World was released that year and displayed a less polished sound. The album was propelled in large part by the massive success of the ballad "Wind of Change". The song muses on the socio-political changes that were occurring in Eastern Europe and other parts of the world at the end of the Cold War. Crazy World is the band's last album to receive gold or platinum certification in the United States. On 21 July 1990 they joined many other guests for Roger Waters' massive performance of The Wall in Berlin. Scorpions performed both versions of "In the Flesh" from The Wall.
Document 6: Megadeth: In mid-2005, Mustaine organized an annual thrash metal festival tour, Gigantour. Megadeth headlined the inaugural tour with acts such as Dream Theater, Nevermore, Anthrax, and Fear Factory. Performances at the Montreal and Vancouver shows were filmed and recorded for a live DVD-and-CD set released in the second quarter of 2006. On October 9, following the successes of The System Has Failed and the Blackmail the Universe world tour, Mustaine announced to a sold-out crowd at the Pepsi Music Rock Festival in Argentina that Megadeth would continue to record and tour. The concert, held at Obras Sanitarias stadium in Buenos Aires in front of 25,000 fans, was filmed and released on DVD as That One Night: Live in Buenos Aires in 2007.In February 2006, bassist James MacDonough left the band over "personal differences". He was replaced by James LoMenzo, who had worked with David Lee Roth, White Lion, and Black Label Society. The new Megadeth lineup made its live debut headlining the Dubai Desert Rock Festival in the United Arab Emirates with Testament. In March, Capitol released a two-disc DVD, Arsenal of Megadeth, which included archive footage, interviews, live shows, and many of the band's music videos. Due to licensing issues, soundtrack and non-Capitol videos were not included. The second Gigantour began during the third quarter of 2006; Megadeth again headlined, this time with Lamb of God, Opeth, Arch Enemy and Overkill. The 2006 tour included three dates in Australia, supported by Soulfly, Arch Enemy, and Caliban.
Document 7: Seek & Destroy: "Seek & Destroy" is a song by the American heavy metal band Metallica and ninth track from their debut studio album, "Kill 'Em All". It was also featured on the demo "No Life 'til Leather". It was the first song the band recorded in a studio. "Seek & Destroy" has been frequently performed at the group's concerts since its live debut in 1982 and had been Metallica's closing song from the Madly in Anger with the World Tour to the Metallica By Request Tour. It is the second-most performed song in the band's history, having been played 1,491 times as of November 2017, ahead of "Creeping Death" (1,461), but behind only "Master of Puppets" (1,561).
Document 8: M2K Mini Tour: The M2K Tour was a mini tour by American heavy metal band Metallica. The tour ran from late December 1999 to early January 2000. During the tour, "Trapped Under Ice" was requested to be played when they were in Chicago by a fan. The song was only played two other times: on November 17, 1984 in Belgium, and on November 18, 1984 in Paris. Metallica also played the New Year's Eve show in Pontiac, Michigan at the Silverdome in front of 50,000 people. At the show, Metallica broadcast the Times Square Ball Drop, ushering in the year 2000, and played the classic Kiss track "Detroit Rock City" alongside Ted Nugent, Kid Rock, and Sevendust. The setlists for these tour dates, like their Sick of the Studio '07 tour, consisted of old songs and songs that they have not played in many years.
Document 9: Rock Band 2: A special "Rock Band 2" premiere event at the 2008 E3 conference was held on July 16, 2008, featuring a performance by surprise special guest The Who, in conjunction with the release of "The Best of The Who" pack as downloadable content. A "Rock Band Live" concert tour toured North America in October and November 2008, and featured bands such as Panic! at the Disco, Dashboard Confessional, Plain White T's and The Cab, as well as local acts selected by radio promotions, contests, and on-site at each show. All acts featured during the tour included songs available as downloadable content for the game prior to the tour. Mark Burnett, along with MTV, sponsored an "Ultimate Rock Band Experience" in Los Angeles, California for the launch of "Rock Band 2", offering the chance for any four-member set of players to participate in the competition; it was speculated that this would be the basis for a new reality television show, although no such show was produced. An early public showing/demo of "Rock Band 2" attended by lead designer Dan Teasdale and other Harmonix Music Systems personnel took place on September 2, 2008, at Ground Kontrol, a video arcade in Portland, Oregon that puts on weekly "Rock Band Tuesdays" events.
Document 10: Scorpions (band): The following year, the Scorpions had an artistic collaboration with the Berlin Philharmonic that resulted in a 10-song album named Moment of Glory.  The album went a long way toward rebuilding the band's reputation after the harsh criticism of Eye II Eye. However, critics accused them of following on the coattails of Metallica's similar collaboration (S&M) with the San Francisco Symphony which had been released the previous year, even though the orchestra had first approached the Scorpions with the idea in 1995.
Document 11: Queen (band): After working on various solo projects during 1988 (including Mercury's collaboration with Montserrat Caballé, Barcelona), the band released The Miracle in 1989. The album continued the direction of A Kind of Magic, using a pop-rock sound mixed with a few heavy numbers. It spawned the European hits "I Want It All", "Breakthru", "The Invisible Man", "Scandal", and "The Miracle". The Miracle also began a change in direction of Queen's songwriting philosophy. Since the band's beginning, nearly all songs had been written by and credited to a single member, with other members adding minimally. With The Miracle, the band's songwriting became more collaborative, and they vowed to credit the final product only to Queen as a group.
Document 12: The M+M's Tour: The M+M's Tour was the sixth concert tour by American recording artist Britney Spears, consisting of six brief shows at clubs in the United States. Spears expressed interest in touring again as early as February 2006. She started rehearsing for a show at House of Blues venues in secret, and pulled out of a surprise performance on April 25, 2007, at Los Angeles nightclub Forty Deuce. After a marquee reading "The M+M's" at the House of Blues in San Diego, California, appeared in late April 2007, media sources identified the act as Spears, and the show quickly sold out. The title, "M+M's" code name was claimed to be Mother (after having two children) and Miss (after being divorced). The tour marked the first time Spears performed live since The Onyx Hotel Tour in June 2004.
Document 13: Metallica: This Monster Lives: The book follows the emotional roller-coaster both he and his film partner Bruce Sinofsky and the band Metallica went through during the creation film. The book takes in the time from Berlinger and Sinofsky's first meeting with Metallica in 1999 to the 2003 Summer Sanitarium Tour. Berlinger and Sinofsky's relationship was at an all time low, exacerbated by Berlinger's decision to direct the disastrous sequel to the Blair Witch. At the start of filming the relationship between the band members, especially between vocalist James Hetfield and drummer Lars Ulrich, is in a similarly perilous position after bassist Jason Newsted quit the band and long standing grudges between the remaining members threaten to escalate past the point of no return.
Document 14: Hard rock: Although Foo Fighters continued to be one of the most successful rock acts, with albums like In Your Honor (2005) reaching number two in the US and UK, many of the first wave of post-grunge bands began to fade in popularity. Acts like Creed, Staind, Puddle of Mudd and Nickelback took the genre into the 2000s with considerable commercial success, abandoning most of the angst and anger of the original movement for more conventional anthems, narratives and romantic songs. They were followed in this vein by new acts including Shinedown and Seether. Acts with more conventional hard rock sounds included Andrew W.K., Beautiful Creatures and Buckcherry, whose breakthrough album 15 (2006) went platinum and spawned the single "Sorry" (2007), which made the Top 10 of the Billboard 100. These were joined by bands with hard rock leanings that emerged in the mid-2000s from the garage rock or post punk revival, including Black Rebel Motorcycle Club and Kings of Leon, and Queens of the Stone Age from the US, Three Days Grace from Canada, Jet from Australia and The Datsuns from New Zealand. In 2009 Them Crooked Vultures, a supergroup that brought together Foo Fighters' Dave Grohl, Queens of the Stone Age's Josh Homme and Led Zeppelin bass player John Paul Jones attracted attention as a live act and released a self-titled debut album that reached the top 20 in the US and UK and the top ten in several other countries.
Document 15: Not in This Lifetime... Tour: While originally slated to commence in Las Vegas on April 8, 2016, a previously unannounced warmup gig at the Troubadour in Los Angeles took place on April 1, 2016. Rumors of the secret show had started the night before, and fans were starting to gather outside the old Tower Records building at Sunset Boulevard in West Hollywood. Rumblings that a ticket sale for the show would take place there started a line of people that grew during the night and into the early morning of April 1. Then, during the morning, the announcement came that the rumors were true and tickets for the club show would go on sale at 12 pm at the Tower Records building. They charged a $10 ``retro ''ticket price for the show. Later in the evening, as the band took the stage at the Troubadour, it was revealed that Melissa Reese, who has previously worked with former drummer Bryan`` Brain'' Mantia on several projects, had replaced longtime second keyboardist Chris Pitman for the tour. During the show at the Troubadour, Rose fell and broke his foot. For the following concerts, Rose was given Dave Grohl's customized throne that Grohl used to perform when he broke his leg at a concert.
