Task: Question Answering
Input (English): Passage: Grunge guitarists "flatly rejected" the virtuoso "shredding" guitar solos that had become the centerpiece of heavy metal songs, instead opting for melodic, blues-inspired solos – focusing "on the song, not the guitar solo". Jerry Cantrell of Alice in Chains stated that solos should be to serve the song, rather than to show off a guitarist's technical skill. In place of the strutting guitar heroes of metal, grunge had "guitar anti-heroes" like Cobain, who showed little interest in mastering the instrument.In Will Byers' article "Grunge committed a crime against music—it killed the guitar solo", in The Guardian, he states that while the guitar solo managed to survive through the punk rock era, it was weakened by grunge. He states that when Kurt Cobain played guitar solos that were a restatement of the main vocal melody, fans realized that they did not need to be a Jimi Hendrix-level virtuoso to play the instrument; he says this approach helped to make music feel accessible by fans in a way not seen since the 1960s folk music movement. The producer of Nirvana's Nevermind, Butch Vig, stated that this album and Nirvana "killed the guitar solo". Soundgarden guitarist Kim Thayil stated he feels in part to be responsible for the "death of the guitar solo"; he said that his punk rocker aspects made him feel that he did not want to solo, so in the 1980s, he preferred to make noise and do feedback during the guitar solo. Baeble Music calls the grunge guitar solos of the 1990s "..raw", "sloppy" and "basic".Not all sources support the "grunge killed the guitar solo" argument. Sean Gonzalez states that Pearl Jam has plentiful examples of guitar solos. Michael Azerrad praises the guitar playing of Mudhoney's Steve Turner, calling him the "... Eric Clapton of grunge", a reference to the British blues guitarist  who Time magazine has named as number five in their list of "The 10 Best Electric Guitar Players". Pearl Jam guitarist Mike McCready has been praised for his blues-influenced, rapid licks. The Smashing Pumpkins' guitarist Billy Corgan has been called the "... arena rock genius of the '90s" for pioneering guitar playing techniques and showing through his playing skill that grunge guitarists do not have to be sloppy players to rebel against mainstream music. Thayil stated that when other major grunge bands, such as Nirvana, were reducing their guitar solos, Soundgarden responded by bringing back the solos. 
Question: What is the full name of the person whose playing skill demonstrated that grunge guitarists do not have to be sloppy players to rebel against mainstream music?
Output (English): Billy Corgan.
