Problem: Aleksandr Isayevich Solzhenitsyn (; 11 December 1918 - 3 August 2008) was a Russian novelist, historian, and short story writer. He was an outspoken critic of the Soviet Union and communism and helped to raise global awareness of its Gulag forced labor camp system. He was allowed to publish only one work in the Soviet Union, One Day in the Life of Ivan Denisovich (1962), in the periodical Novy Mir.

During the war, Solzhenitsyn served as the commander of a sound-ranging battery in the Red Army, was involved in major action at the front, and was twice decorated. He was awarded the Order of the Red Star on 8 July 1944 for sound-ranging two German artillery batteries and adjusting counterbattery fire onto them, resulting in their destruction. A series of writings published late in his life, including the early uncompleted novel Love the Revolution!, chronicles his wartime experience and his growing doubts about the moral foundations of the Soviet regime. While serving as an artillery officer in East Prussia, Solzhenitsyn witnessed war crimes against local German civilians by Soviet military personnel. The noncombatants and the elderly were robbed of their meager possessions and women and girls were gang-raped to death. A few years later, in the forced labor camp, he memorized a poem titled "Prussian Nights" about these incidents. In this poem, which describes the gang-rape of a Polish woman whom the Red Army soldiers mistakenly thought to be a German, the first-person narrator comments on the events with sarcasm and refers to the responsibility of official Soviet writers like Ilya Ehrenburg. In The Gulag Archipelago, Solzhenitsyn wrote, "There is nothing that so assists the awakening of omniscience within us as insistent thoughts about one's own transgressions, errors, mistakes. After the difficult cycles of such ponderings over many years, whenever I mentioned the heartlessness of our highest-ranking bureaucrats, the cruelty of our executioners, I remember myself in my Captain's shoulder boards and the forward march of my battery through East Prussia, enshrouded in fire, and I say: 'So were we any better?'"

What kind of actions did he witness in these crimes?

Answer with quotes: The noncombatants and the elderly were robbed of their meager possessions and women and girls were gang-raped to death.

Background: Fall Out Boy is an American rock band formed in Wilmette, Illinois, a suburb of Chicago, in 2001. The band consists of lead vocalist and rhythm guitarist Patrick Stump, bassist Pete Wentz, lead guitarist Joe Trohman, and drummer Andy Hurley. The band originated from Chicago's hardcore punk scene, with which all members were involved at one point. The group was formed by Wentz and Trohman as a pop punk side project of the members' respective hardcore bands, and Stump joined shortly thereafter.
Context: Fall Out Boy have been instrumental in the careers of other artists, such as Panic! at the Disco, whom Pete Wentz signed to his record label, Decaydance Records, in late 2004. Several artists, such as You Me at Six and Taylor Swift, have created or performed covers of Fall Out Boy songs as a homage to the band. The Fall Out Boy band members were the first inductees to the "Hall of Wood" at the 2015 MtvU Woodie Awards and performed a medley of five songs at the ceremony. This honor is given to artists who have used MTV Woodie Awards as a "launching pad" in achieving chart topping success within their musical careers, thus influencing up and coming bands. The award also recognizes bands "sticking to their roots" and "maintaining their loyal fan base". The group had won the Woodie Award for Streaming for "Grand Theft Autumn" at the first ceremony in 2004. In a list of the 50 greatest pop-punk albums of all time, Rolling Stone placed Fall Out Boy's 2003 album Take This To Your Grave as the fifth greatest, citing it as "[ushering] in a whole new, genre-blurring scene, in which heavy riffs and a screamo aesthetic mingled with old-fashioned teen heartbreak". In a similar list, Kerrang! magazine placed Take This To Your Grave at number 11 out of 51, describing it as a "blueprint for both break-up records and timeless pop-punk". In 2017, Fall Out Boy were announced as the first winners of Rock Sound's Hall of Fame Award as part of the Rock Sound Awards. In an interview accompanying the band's win, Patrick Stump stated one reason for the band's success is Sugar, We're Goin Down, explaining that the "song changed my life, I have a music career in a large part due to that song". In 2009, Phoenix New Times writer Martin Cizmar had described Sugar, We're Goin Down as possibly "the most listened-to emo track of all time".

Question:
Skid Row is an American heavy metal band, formed in 1986 in Toms River, New Jersey. The group achieved commercial success in the late 1980s and early 1990s, with its first two albums Skid Row (1989) and Slave to the Grind (1991) certified multi-platinum, the latter of which reached number one on the Billboard 200. The band's third album Subhuman Race (1995) was also critically acclaimed, but failed to repeat the success of its predecessors. During this period, the band consisted of bassist Rachel Bolan, guitarists Dave Sabo and Scotti Hill, drummer Rob Affuso, and frontman Sebastian Bach.
Skid Row, released in January 1989, was an instant success. The record went 5x platinum on the strength of the Top 10 singles "18 and Life" and "I Remember You". Skid Row supported the album by opening for Bon Jovi on their New Jersey tour. As part of the six-month tour, Skid Row played its first ever UK gig supporting Bon Jovi's outdoor show at Milton Keynes Bowl on August 19, 1989. The next day, Skid Row played a successful club show at London's Marquee Club in Charing Cross Road. Skid Row also took part in the Moscow Music Peace Festival, which was set up to keep McGhee out of jail. McGhee was facing drug trafficking charges, and therefore set up an anti-drug/peace concert in Russia, featuring a few of the artists that he and his brother managed. Skid Row returned to the UK three months later, opening for Motley Crue on their European Dr. Feelgood Tour in early November 1989 with White Lion. That was followed by a UK headlining tour culminating in a show at London's Hammersmith Odeon, with Vain supporting. In what is referred to as "The Bottle Incident" by fans of the band, Bach was hit onstage with a bottle thrown from the crowd at a concert in Springfield, Massachusetts, where Skid Row was opening for Aerosmith on December 27, 1989. Bach threw the bottle back, hitting a girl (not the thrower), so he jumped on the crowd to beat the person who can be seen on a tour video released by Skid Row called Oh Say Can You Scream in 1990. Shortly thereafter, at another show, Bach put on a T-shirt proclaiming the anti-gay slogan "AIDS Kills Fags Dead". The shirt was given to him by a fan, but Bach eventually expressed regret over the incident, claiming that he did not read the slogan before putting the shirt on. The band also recorded a cover of the Sex Pistols' "Holidays in the Sun" for the Make A Difference Foundation release Stairway to Heaven/Highway to Hell.
