Grohl delivered a keynote speech at the 2013 South by Southwest conference in Austin Texas, U.S. on the morning of March 14. Lasting just under an hour, the speech covered Grohl's musical life from his youth through to his role with the Foo Fighters and emphasized the importance of each individual's voice, regardless of who the individual is: "There is no right or wrong—there is only your voice... What matters most is that it's your voice. Cherish it. Respect it. Nurture it. Challenge it. Respect it." Grohl said during the speech that Psy's "Gangnam Style" was one of his favorite songs of the past decade. He also referenced Edgar Winter's instrumental "Frankenstein" as the song that made him want to become a musician.
