Beloved for their theatrical hard rock flash and for frontman Freddie Mercury's operatic voice, rock band Queen debuted in 1973. Listeners adored the UK group's unique take on prog, which eschewed the genre's typical complex time signatures in favor of dramatic flourish, high-concept themes, and classical arrangements. By the ‘80s, Queen evolved into a bombastic, straight-ahead hard rock band boasting four strong songwriters. Together, they ensured that the intricacy of their song structures never diminished, even as Queen became best known for songs packed with driving momentum.
