King Diamond is on tour now with Uncle Acid and Idle Hands as he gears up to release his new album The Institute in 2020 via Metal Blade, and now he has officially released the new single "Masquerade of Madness," which he's been playing live all year. It's pretty much classic King Diamond -- militant rhythms, soaring falsettos, shredding solos -- and it sounds great. Listen below.

The King Diamond tour just hit Brooklyn's Kings Theatre last night, 11/7 (where King Diamond performed this song), and we'll have more on that very soon but meanwhile you can check out the setlist below. (UPDATE: Pics/review HERE.) Next year, King Diamond's classic band Mercyful Fate will reunite for their first shows in 20+ years.
