One of the most successful musical acts of all time, Queen is second only to the Beatles in their home country Britain, in record sales and memorabilia. Queen became vastly popular in the mid-late '70's with classic hits such as "Killer Queen", "Bohemian Rhapsody", and "We Will Rock You". Their flamboyant and energetic stage presence made them the forefathers of "Glam Rock" and "Stadium Rock". Queen was really hitting their peak in the early 80's when their frontman Freddie Mercury succumbed to HIV. This saw the unfortunate end for one of Rock's greatest bands.
