"Widely regarded as one of the finest vocalists in all of metal (who possesses a multi-octave range), Danish theatrical rocker King Diamond first rose to prominence as a member of gothic black metal group Mercyful Fate before launching a solo career in 1986. Known for his elastic falsetto, distinctive face-paint, occult leanings, femur- and tibia bone-adorned microphone stand, and seminal 1987 concept album Abigail, Diamond is one of late 20th and early 21st century most iconic heavy metal figures, issuing a slew of quality, narrative-driven albums, [one] of which earned a Grammy nomination."
