The British rock band Queen was well known for its diverse music style in contemporary rock. Their large sound systems, lighting rigs, innovative pyrotechnics and extravagant costumes often gave shows a theatrical nature. Artists such as Bob Geldof, George Michael, David Bowie, Michael Jackson and Robbie Williams have expressed admiration for lead singer Freddie Mercury's stage presence.
Queen wrote certain songs, such as "We Will Rock You" and "We Are the Champions", with the goal of audience participation. "Radio Ga Ga" came to inspire synchronized hand-clapping (this routine, originating from the song's video, was the invention of the video's director, David Mallet). This influenced Queen's appearance at Live Aid, where the 72,000-person crowd at Wembley Stadium would sing loudly and clap their hands in unison. Queen's performance at Live Aid was later voted the greatest live show of all time by a group of over 60 musicians, critics, and executives in a poll conducted by Channel 4.[1]
