Task: Question Answering
Input (English): Passage: In 1996 the Pumpkins undertook an extended world tour in support of Mellon Collie. Corgan's look during this period—a shaved head, a long sleeve black shirt with the word "Zero" printed on it, and silver pants—became iconic. That year, the band also made a guest appearance in an episode of The Simpsons, "Homerpalooza". With considerable video rotation on MTV, major industry awards, and "Zero" shirts selling in many malls, the Pumpkins were considered one of the most popular bands of the time. But the year was far from entirely positive for the band. In May, the Smashing Pumpkins played a gig at the Point Theatre in Dublin, Ireland. Despite the band's repeated requests for moshing to stop, a seventeen-year-old fan named Bernadette O'Brien was crushed to death. The concert ended early and the following night's performance in Belfast was cancelled out of respect for her. However, while Corgan maintained that moshing's "time [had] come and gone", the band would continue to request open-floor concerts throughout the rest of the tour.The band suffered a personal tragedy on the night of July 11, 1996, when touring keyboardist Jonathan Melvoin and Chamberlin overdosed on heroin in a hotel room in New York City. Melvoin died, and Chamberlin was arrested for drug possession. A few days later, the band announced that Chamberlin had been fired as a result of the incident. The Pumpkins chose to finish the tour, and hired drummer Matt Walker and keyboardist Dennis Flemion. Corgan later said the decision to continue touring was the worst decision the band had ever made, damaging both their music and their reputation. Chamberlin admitted in a 1994 Rolling Stone cover story that in the past he'd "gotten high in every city in this country and probably half the cities in Europe." But in recent years, he had reportedly been clean. On July 17, the Pumpkins issued a statement in which they said, "For nine years we have battled with Jimmy's struggles with the insidious disease of drug and alcohol addiction. It has nearly destroyed everything we are and stand for. … We wish [him] the best we have to offer". Meanwhile, the band had given interviews since the release of Mellon Collie stating that it would be the last conventional Pumpkins record, and that rock was becoming stale. James Iha said at the end of 1996, "The future is in electronic music. It really seems boring just to play rock music.".
