RANKED: The Top 25 Rock Vocalists of All-Time

The heavy metal operatic vocal stylings of Bruce Dickinson — lead singer of Iron Maiden — make him a no-brainer as one of Rock N’ Roll’s top vocalists. With an impressive vocal range of over four octaves, Dickinson joined Iron Maiden in 1981 (replacing original lead singer Paul Di’Anno). During a 2003 festival performance, Dickinson held an astonishing 41-second note — a seemingly impossible feat that will leave you gasping for air just listening to it.
