Background: Al Jolson was born as Asa Yoelson (Yiddish: asa yvlsan) in the Jewish village of Srednike (Yiddish: sr`dnyq) now known as Seredzius, near Kaunas in Lithuania, then part of the Russian Empire. He was the fifth and youngest child of Moses Rubin Yoelson (1858 - December 23, 1945) and Nechama "Naomi" Cantor (1858 - February 6, 1895); his four siblings were Rose, Etta, another sister who died in infancy, and Hirsch (Harry). Jolson claimed not to know when he was born, and later chose to claim he was born on May 26, 1886.
Context: According to Esquire magazine, "J.J. Shubert, impressed by Jolson's overpowering display of energy, booked him for La Belle Paree, a musical comedy that opened at the Winter Garden in 1911. Within a month Jolson was a star. From then until 1926, when he retired from the stage, he could boast an unbroken series of smash hits."  On March 20, 1911, Jolson starred in his first musical revue at the Winter Garden Theater in New York City, La Belle Paree, greatly helping to launch his career as a singer. The opening night drew a huge crowd to the theater, and that evening Jolson gained audience popularity by singing old Stephen Foster songs in blackface. In the wake of that opening night, Jolson was given a position in the show's cast. The show closed after 104 performances, and during its run Jolson's popularity grew greatly. Following La Belle Paree, he accepted an offer to perform in the musical Vera Violetta. The show opened on November 20, 1911 and, like La Belle Paree, was a phenomenal success. In the show, Jolson again sang in blackface and managed to become so popular that his weekly salary of $500 (based on his success in La Belle Paree) was increased to $750.  After Vera Violetta ran its course, Jolson starred in another musical, The Whirl of Society, propelling his career on Broadway to new heights. During his time at the Winter Garden, Jolson would tell the audience, "You ain't heard nothing yet" before performing additional songs. In the play, Jolson debuted his signature blackface character, "Gus." The play was so successful that Winter Garden owner Lee Shubert agreed to sign Jolson to a seven-year contract with a salary of $1,000 a week. Jolson would reprise his role as "Gus" in future plays and by 1914 achieved so much popularity with the theater audience that his $1,000-a-week salary was doubled to $2,000 a week. In 1916, Robinson Crusoe, Jr. was the first musical in which he was featured as the star character. In 1918, Jolson's acting career would be pushed even further after he starred in the hit musical Sinbad.  It became the most successful Broadway musical of 1918 and 1919. A new song was later added to the show that would become composer George Gershwin's first hit recording--"Swanee". Jolson also added another song, "My Mammy," to the show. By 1920, Jolson had become the biggest star on Broadway.
Question: What did Jolson do after the production?
Answer: Following La Belle Paree, he accepted an offer to perform in the musical Vera Violetta.

Background: 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.
Context: 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.
