Mercury was noted for his live performances, which were often delivered to stadium audiences around the world. He displayed a highly theatrical style that often evoked a great deal of participation from the crowd. A writer for The Spectator described him as "a performer out to tease, shock and ultimately charm his audience with various extravagant versions of himself". David Bowie, who performed at the Freddie Mercury Tribute Concert and recorded the song "Under Pressure" with Queen, praised Mercury's performance style, saying: "Of all the more theatrical rock performers, Freddie took it further than the rest... he took it over the edge. And of course, I always admired a man who wears tights. I only saw him in concert once and as they say, he was definitely a man who could hold an audience in the palm of his hand."
One of Mercury's most notable performances with Queen took place at Live Aid in 1985, during which the entire stadium audience of 72,000 people clapped, sang and swayed in unison. Queen's performance at the event has since been voted by a group of music executives as the greatest live performance in the history of rock music. The results were aired on a television program called "The World's Greatest Gigs". In reviewing Live Aid in 2005, one critic wrote, "Those who compile lists of Great Rock Frontmen and award the top spots to Mick Jagger, Robert Plant, etc all are guilty of a terrible oversight. Freddie, as evidenced by his Dionysian Live Aid performance, was easily the most godlike of them all."
Over the course of his career, Mercury performed an estimated 700 concerts in countries around the world with Queen. A notable aspect of Queen concerts was the large scale involved. He once explained, "We're the Cecil B. DeMille of rock and roll, always wanting to do things bigger and better."
