1. Freddie Mercury
Few people would have qualms about putting Freddie Mercury in first place on a list of top rock vocalists. Mercury was one part rockstar and one part operatic singer who could hit notes high enough to scrape heaven. No one (except Adam Lambert who is doing a fine job filling in for the frontman) could hope to measure up to Mercury’s sheer firepower behind the microphone. Despite being gone for over 30 years now, Mercury stills holds the crown for one of the best rock vocalists the genre has ever seen.
