10 Best Replacement Singers Of All Time

10. John Bush - Anthrax

Out of all the Big 4, bad luck seemed to follow Anthrax around wherever they want. From barely getting signed to Megaforce Records in the early days to being on tour with Metallica during Cliff Burton's death, there was no real end to the setbacks that they had to endure before seeing success. Hell, even when they got the notoriety off of albums like Among the Living, they had to cut ties with Joey Belladonna just a few years later.

After the tumultuous process of creating Persistence of Time, the creative partnership between Belladonna and Scott Ian hit a boiling point, with Ian threatening to quit the band if they didn't find a new singer. Though Joey's upper register fit in perfectly with the chaos down below, they really managed to knock it out of the park by getting John Bush at the beginning of the '90s.

Already a seasoned veteran on the metal scene with Armored Saint, Bush's heavy baritone was much better suited to the kind of music that Anthrax was putting out at the time, almost like he had a lion's roar buried inside him. Starting off with the track Only, Bush hit the ground running and never seemed to stop, staying the course and getting even heavier as time went on with records like We've Come For You All. Although Joey might be back in the band now, it's not like Anthrax were necessarily hurting during those years of absence.
