input: Born with a twin brother, Gustavo, Barros Schelotto was hence nicknamed El Mellizo ("the twin"). He started playing professionally at the end of 1991 with his hometown team Gimnasia y Esgrima de La Plata, where he scored 45 goals in 181 matches in five seasons and in 1993 won the AFA Centenario Cup. On 14 September 1997 he transferred to Primera Division Argentina powerhouse Boca Juniors, for whom he played for almost 10 years. He was considered an idol by Boca fans and in his later years at the club showed his experience whenever he stepped on the pitch. Barros Schelotto remains one of Boca's top scorers in international matches with 25 goals, just one goal behind former teammate Martin Palermo.  In 1996, he was offered to play for River Plate, but after club icon Enzo Francescoli was not happy with the potential signing, the deal collapsed. In mid-1997, Boca Juniors showed interest for him and his brother Gustavo. It was like that that Barros Schelotto twins arrived to Boca teaming up to a former rival: Martin Palermo, Gimnasia's archrival Estudiantes de La Plata former player. The three of them were repeatedly recommended to Boca by Diego Maradona, who was playing his last season for the Buenos Aires team, retiring on October the same year. Once in Boca, he made his debut as a substitute for Claudio Caniggia, scoring on 14 September 1997 against Newell's Old Boys in a 2-1 victory.  With Carlos Bianchi as Boca Juniors' coach, Barros Schelotto got his traditional 7 shirt and kept it until 2006-07 season. He and former rival Martin Palermo became a successful attacking duo, who highly contributed in the 1998-99 title-winning season. He missed the 2001 and 2003 clubs international achievements due to injuries. In 2003, he was a key piece in the winning Copa Libertadores side, with his peak performance at the Round of 16 match against Brazilian team Paysandu, where he scored a hat-trick and assisted Marcelo Delgado's goal. In the second half of 2003 he again suffered from injuries and could only play for 46 minutes in the Copa Intercontinental winning match against AC Milan, when he replaced Carlos Tevez. With Alfio Basile as Boca coach, his participation in the first team was gradually lowering. He even was out of some first team matches and had to play for the second team to maintain his performance level. He scored 87 goals in 302 games for Boca Juniors.

Question: Slayer is an American thrash metal band from Huntington Park, California. The band was formed in 1981 by vocalist/bassist Tom Araya and guitarists Kerry King and Jeff Hanneman. Slayer's fast and aggressive musical style made them one of the founding "big four" bands of thrash metal, alongside Metallica, Megadeth and Anthrax. Slayer's current lineup comprises King, Araya, drummer Paul Bostaph and guitarist Gary Holt.

Following the success of Hell Awaits, Slayer was offered a recording contract with Russell Simmons and Rick Rubin's newly founded Def Jam Records, a largely hip hop-based label. The band accepted and with an experienced producer and major label recording budget, the band underwent a sonic makeover for their third album Reign in Blood resulting in shorter, faster songs with clearer production. Gone were the complex arrangements and long songs featured on Hell Awaits, ditched in favor of stripped down, hardcore punk influenced song structures.  Def Jam's distributor, Columbia Records, refused to release the album due to the song "Angel of Death" which detailed Holocaust concentration camps and the human experiments conducted by Nazi physician Josef Mengele. The album was distributed by Geffen Records on October 7, 1986. However, due to the controversy, Reign in Blood did not appear on Geffen Records' release schedule. Although the album received virtually no radio airplay, it became the band's first to enter the Billboard 200, debuting at number 94, and the band's first album certified gold in the United States.  In October 1986, Slayer embarked on the Reign in Pain world tour, with Overkill in the US, and Malice in Europe. The band was added as the opening act on W.A.S.P.'s US tour, but just one month in, drummer Lombardo left the band: "I wasn't making any money. I figured if we were gonna be doing this professionally, on a major label, I wanted my rent and utilities paid." To continue with the tour, Slayer enlisted Tony Scaglione of Whiplash. However, Lombardo was convinced by his wife to return in 1987. At the insistence of Rubin, Slayer recorded a cover version of Iron Butterfly's "In-A-Gadda-Da-Vida" for the film Less Than Zero. Although the band was not happy with the final product, Hanneman deeming it "a poor representation of Slayer" and King labeling it "a hunk of shit," it was one of their first songs to garner radio airplay.
