Question: Who collaborated with the performer of 2 of One?

full_context: Document 1: 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 2: 2 of One: 2 of One is a video album by the American thrash metal band Metallica. It was released on June 6, 1989, through Elektra Entertainment and features two versions of the group's first music video "One", from its fourth studio album "...And Justice for All". The music video was directed by Bill Pope and Michael Salomon and was filmed in Los Angeles, California.
Document 3: Jump in the Fire: "Jump in the Fire" is a song by American heavy metal band Metallica. It was released as the second and final single from their debut album, "Kill 'Em All". The single was accompanied by fake live performances of "Phantom Lord" and "Seek & Destroy" which were alternate studio recordings with sounds of a crowd overdubbed in.
Document 4: Damaged Justice: Damaged Justice was the fourth concert tour by the American thrash metal band Metallica. It began on September 11, 1988 and ended on October 8, 1989. The name is believed to be inspired either by the cover of its fourth studio album "...And Justice for All", or by the song "Damage, Inc." from the group's previous album, "Master of Puppets".
Document 5: 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 6: 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 7: 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 8: Metallica: Metallica is an American heavy metal band. The band was formed in 1981 in Los Angeles, California, by drummer Lars Ulrich and vocalist/guitarist James Hetfield, and has been based in San Francisco, California for most of its career. The group's fast tempos, instrumentals and aggressive musicianship made them one of the founding "big four" bands of thrash metal, alongside Megadeth, Anthrax and Slayer. Metallica's current lineup comprises founding members Hetfield and Ulrich, longtime lead guitarist Kirk Hammett and bassist Robert Trujillo. Guitarist Dave Mustaine (who went on to form Megadeth) and bassists Ron McGovney, Cliff Burton and Jason Newsted are former members of the band.
Document 9: Ride the Lightning: Ride the Lightning is the second studio album by American heavy metal band Metallica, released on July 27, 1984, by the independent record label Megaforce Records. The album was recorded in three weeks with producer Flemming Rasmussen at the Sweet Silence Studios in Copenhagen, Denmark. The artwork, based on a concept by the band, depicts an electric chair being struck by lightning flowing from the band logo. The title was taken from a passage in Stephen King's novel "The Stand". Although rooted in the thrash metal genre, the album showcased the band's musical growth and lyrical sophistication. This was partly because bassist Cliff Burton introduced the basics of music theory to the rest of the band and had more input in the songwriting. Instead of relying heavily on fast tempos as on its debut "Kill 'Em All", Metallica broadened its approach by employing acoustic guitars, extended instrumentals, and more complex harmonies. The overall recording costs were paid by Metallica's European label Music for Nations because Megaforce was unable to cover it. It was the last album to feature songwriting contributions from former lead guitarist Dave Mustaine, and the first to feature contributions from his replacement, Kirk Hammett.
Document 10: 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 11: 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 12: Metallica (album): Metallica (commonly known as The Black Album) is the self - titled fifth studio album by American heavy metal band Metallica. Released on August 12, 1991 by Elektra Records, it received widespread critical acclaim and became the band's best - selling album. Metallica produced five singles that are considered to be among the band's best - known songs, which include ``Enter Sandman '',`` The Unforgiven'', ``Nothing Else Matters '',`` Wherever I May Roam'', and ``Sad but True ''. A sixth song,`` Do n't Tread on Me'', was also issued to rock radio shortly after the album's release, but the song did not receive a commercial single release. The album marked a change in the band's sound from the thrash metal style of the previous four albums to a slower and heavier one rooted in heavy metal. Metallica promoted the album with a series of tours. In 2003, the album was ranked number 252 on Rolling Stone's 500 greatest albums of all time.
Document 13: For Whom the Bell Tolls (Metallica song): "For Whom the Bell Tolls" is a song by American thrash metal band Metallica. It was first released on the group's second album, "Ride the Lightning" (1984). In 1985, Elektra Records released it as a promotional single, with both an edited and full-length versions. The song is generally regarded as one of their most popular; by March 2018, it ranked number five on Metallica's live performance count. Several live albums and video albums include the song.
Document 14: 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 15: 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.
