Problem: Background: Mario Lanza (born Alfredo Arnold Cocozza; January 31, 1921 - October 7, 1959) was an American tenor of Italian ancestry, and an actor and Hollywood film star of the late 1940s and the 1950s. Lanza began studying to be a professional singer at the age of 16. After appearing at the Hollywood Bowl in 1947, Lanza signed a seven-year film contract with Louis B. Mayer, the head of Metro-Goldwyn-Mayer, who saw his performance and was impressed by his singing.
Context: Lanza was the first RCA Victor Red Seal artist to win a gold disc and the first artist to sell 2 1/2 million albums  Lanza was referred to by some sources as the "new Caruso" after his "instant success" in Hollywood films, while MGM hoped he would become the movie studio's "singing Clark Gable" for his good looks and powerful voice.  In 1994, outstanding tenor Jose Carreras paid tribute to Lanza during a worldwide concert tour, saying of him, "If I'm an opera singer, it's thanks to Mario Lanza." His equally outstanding colleague Placido Domingo echoed these comments in a 2009 CBS interview with, "Lanza's passion and the way his voice sounds are what made me sing opera. I actually owe my love for opera ... to a kid from Philadelphia."  Even today "the magnitude of his contribution to popular music is still hotly debated," and because he appeared on the operatic stage only twice, many critics feel that he needed to have had more "operatic quality time" in major theaters before he could be considered a star of that art form. His films, especially The Great Caruso, influenced numerous future opera stars, including Joseph Calleja, Jose Carreras, Placido Domingo and Luciano Pavarotti. According to opera historian Clyde McCants, "Of all the Hollywood singers who performed operatic music ... the one who made the greatest impact was Mario Lanza." Hollywood gossip columnist Hedda Hopper concluded that "there had never been anyone like Mario, and I doubt whether we shall ever see his like again".
Question: Did he influence others as well?
Answer: According to opera historian Clyde McCants, "Of all the Hollywood singers who performed operatic music ... the one who made the greatest impact was Mario Lanza.

Problem: Background: Propagandhi is a Canadian punk rock band formed in Portage la Prairie, Manitoba in 1986 by guitarist Chris Hannah and drummer Jord Samolesky. The band is currently located in Winnipeg, Manitoba and completed by bassist Todd Kowalski and guitarist Sulynn Hago. While their earlier work was aligned with the punk rock and skate punk tradition, in later years Propagandhi records have moved towards a heavier and more technical heavy metal-influenced sound. Both in their lyrics and hands-on activism, the band's members champion various left wing and anarchist causes and veganism, and have taken a vocal stance against human rights violations, sexism, racism, nationalism, homophobia, imperialism, capitalism and organized religion.
Context: Propagandhi released the album Potemkin City Limits on October 18, 2005. Like its predecessor, the album features multimedia content, with a number of PDF files on topics such as participatory economics and veganism, and links to websites of organizations that Propagandhi support. The album's opening track, "A Speculative Fiction", won the 2006 SOCAN Songwriting Prize by online vote. Propagandhi pledged to use the $5000 prize to make donations to the Haiti Action Network and The Welcome Place, an organization in Winnipeg for which they'd previously done volunteer work which helps refugees start new lives in Manitoba.  Hannah briefly adopted the pseudonym Glen Lambert in the run-up to and immediate aftermath of the release of Potemkin City Limits, causing confusion among some fans, reviewers, and commentators; the band concluded the prank by announcing on 14 August 2006 that Glen Lambert had been dismissed and would be replaced by "former" member Chris Hannah. This coincided with the addition of second guitarist David Guillas, marking the band's first four-piece lineup in their then-twenty year career. Guillas, nicknamed "The Beaver", was a former member of two Winnipeg-based rock outfits, Giant Sons and Rough Music. Hannah had previously stated that he had been a fan of, and influenced by, Guillas' work in Giant Sons.  In 2007, the band released a DVD entitled Live from Occupied Territory, which features a recording of their set at The Zoo in Winnipeg on July 19, 2003. Proceeds of the DVD benefit the Grassy Narrows blockade and the Middle East Children's Alliance. Included on the DVD are two full-length documentaries: Peace, Propaganda and the Promised Land, and As Long as the Rivers Flow.
