Adding to that Bon and Brian are also top-tier vocalists. Both have an expansive 3 octave, 4 note vocal range, Bon's being A2-E6, Brian's being D2-A5. Bon had a helium tenor with a great, gritty timbre and tonality, something he only lost at the outermost reaches of his fantastic vocal range (usually around the the upper second and fifth octaves). He had a similar ability to Steve Grimmett in terms of how seamlessly and agilely he could glide to larynx-shattering pitches without losing much, if any, of his resonance, volume, grit, or power. Brian is feral beast when he's at the top of his vocal game. Man can howl the upper fifth octave loud enough to be heard in the the presence of a fully cranked AC/DC, and he's got an exceptional, ultra-manly low range that even Bon didn't possess. He doesn't just hit these notes, he attacks them. Most singers would shit enough bricks to contruct and reconstruct all of NYC four times over at the prospect of singing, say, Snowballed, Let Me Put My Love Into You, or Shoot To Thrill with even 3/4 the conviction, grit, tonal uniqueness, and power that Johnson pulled them of with.
