#2 The 411: Freddie Mercury and Queen managed to take glam rock to the arenas. Queen is often considered one of the best rock bands of all time and with good reason. You must give a good portion of that acclaim to their lead man Freddie Mercury. While others on the list are great glam icons, Mercury's voice was glam in itself. His voice screams confidence and the larger than life persona that was the very theatrical Freddie Mercury.
