Freddie Mercury dominated the flamboyant "Glam-rock" style of mid-1970s rock 'n' roll performances with a dynamic voice and an electrifying stage presence unmatched by his peers. As the lead singer of the supergroup, Queen, Mercury commanded and entranced fans all over the world with a powerful, four-octave singing range, coupled with a shocking array of skintight costumes. He effortlessly hit and sustained high notes that were usually limited to female opera stars, but also snarled through the band's hard-hitting songs with his powerful tenor voice. On stage, he moved with energy and bravado as he acted out some of their biggest and most aggressive hits like "Killer Queen" (1974), "We Will Rock You" (1977), and "We Are the Champions" (1977). Mercury wrote music that combined a variety of influences - from blues, funk, disco and a touch of vaudeville - with authority and flair. But by far, the most timeless song that he would write was "Bohemian Rhapsody" (1975), a multilayered hard rock gem infused with an operatic feel. While Queen produced its best work during the mid to late 1970s, its charismatic front man kept on singing throughout the 1980s - at his apex, wowing billions of people watching 1985's benefit concert, Live Aid - before shockingly dying in 1991 from the AIDS virus. Fans and his band members grieved the loss of Freddy, as he was not an easy frontman to replace. However, even in death, Mercury continued to reach new generations of fans with his enduring and unrivaled legacy as one of music's consummate stage entertainers and arguably the greatest singer in rock 'n' roll history.
