Background: The Houston Livestock Show and Rodeo, also called RodeoHouston or abbreviated HLSR, is the largest livestock exhibitions and rodeo in the world. It also includes one of the richest regular-season rodeo events. It has been held at NRG Stadium in Houston, Texas, since 2003. It was previously held in the Astrodome.
Context: One of the largest draws for the Houston Livestock Show and Rodeo is the 20 consecutive evenings of rodeo and concert, held in NRG Stadium. Tickets are relatively inexpensive, averaging about $29 in 2016, and also grant admission to the livestock show and fairgrounds. More than 43,000 season tickets are sold every year, with the remaining seats 30,000 seats available for individual-show sale. Members of the HLSR are given an opportunity to buy individual tickets before the general public.  RodeoHouston is run independently of the Professional Rodeo Cowboys Association (PRCA). It offers one of the largest prize purses in North America, over $2 million, but the winnings do not count towards the competitors' qualification for the PRCA National Finals Rodeo. RodeoHouston is an invitational, featuring 280 of the top professional cowboys. They compete in a playoff format, with the ultimate champion in each event earning $50,000. On the final evening, the rodeo hosts the Cinch SuperShootout. Champions from each of the top 10 rodeos in North America are invited to compete as teams in a subset of rodeo events. The finals and the SuperShoot are televised on Fox Sports.  After the professional rodeo concludes, children are given an opportunity to compete. Each evening, 30 high school students from across the state compete in the calf scramble. They are given the opportunity to chase down (on foot) and catch one of 15 calves, put a halter on them, and drag them back to the center of the stadium. Winners are given money to purchase their own heifer or steer to show the following year. Immediately following the calf scramble is mutton busting. Five- and six-year-olds wearing protective gear try to ride a sheep across a portion of the arena. On the last night of the rodeo, the winners from each of the previous evenings compete again to see who will become grand champion.  A rotating stage is then brought into the arena for the nightly concert. The majority of evenings are performances by country music singers, although several nights are dedicated to pop or rock music. The annual Tejano music night generally draws the largest crowds. The winner of the annual Mariachi Invitational competition is invited to perform onstage with the Tejano acts.
Question: Are the concerts outside?
Answer: A rotating stage is then brought into the arena for the nightly concert.

Problem: Background: Janis Lyn Joplin (; January 19, 1943 - October 4, 1970) was an American rock singer and songwriter; one of the most successful and widely-known female rock stars of her era. After releasing three albums, she died of a heroin overdose at the age of 27. A fourth album, Pearl, was released in January 1971, just over three months after her death.
Context: Joplin appeared at Woodstock starting at approximately 2:00 a.m., on Sunday, August 17, 1969. Joplin informed her band that they would be performing at the concert as if it were just another gig. On Saturday afternoon, when she and the band were flown by helicopter with the pregnant Joan Baez and Baez's mother from a nearby motel to the festival site and Joplin saw the enormous crowd, she instantly became extremely nervous and giddy. Upon landing and getting off the helicopter, Joplin was approached by reporters asking her questions. She referred them to Caserta as she was too excited to speak. Initially Joplin was eager to get on the stage and perform, but was repeatedly delayed as bands were contractually obliged to perform ahead of Joplin. Faced with a ten-hour wait after arriving at the backstage area, Joplin shot heroin and drank alcohol with Caserta, and by the time of reaching the stage, Joplin was "three sheets to the wind". During her performance, Joplin's voice became slightly hoarse and wheezy, and she struggled to dance.  Joplin pulled through, however, and engaged frequently with the crowd, asking them if they had everything they needed and if they were staying stoned. The audience cheered for an encore, to which Joplin replied and sang "Ball and Chain". Pete Townshend, who performed with the Who later in the same morning after Joplin finished, witnessed her performance and said the following in his 2012 memoir: "She had been amazing at Monterey, but tonight she wasn't at her best, due, probably, to the long delay, and probably, too, to the amount of booze and heroin she'd consumed while she waited. But even Janis on an off-night was incredible."  Janis remained at Woodstock for the remainder of the festival. Starting at approximately 3:00 a.m. on Monday, August 18, Joplin was among many Woodstock performers who stood in a circle behind Crosby, Stills & Nash during their performance, which was the first time anyone at Woodstock ever had heard the group perform with Neil Young. This information was published by David Crosby in 1988. Later in the morning of August 18, Joplin and Joan Baez sat in Joe Cocker's van and witnessed Hendrix's close-of-show performance, according to Baez's memoir And a Voice to Sing With (1989).  Still photographs in color show Joplin backstage with Grace Slick the day after Joplin's performance, wherein Joplin appears to be very happy. Joplin was ultimately unhappy with her performance, however, and blamed Caserta. Her singing was not included (by her own insistence) in the 1970 documentary film or the soundtrack for Woodstock: Music from the Original Soundtrack and More, although the 25th anniversary director's cut of Woodstock includes her performance of "Work Me, Lord". The documentary film of the festival that was released to theaters in 1970 includes, on the left side of a split screen, 37 seconds of footage of Joplin and Caserta walking toward Joplin's dressing room tent.
Question: Was her singing not included because she was not happy with her performance at woodstock?
Answer:
Joplin was ultimately unhappy with her performance,
