Psycho Las Vegas 2017 will be taking place from August 18th through August 20th at the Hard Rock Hotel And Casino Las Vegas in Las Vegas, Nevada, and the legendary King Diamond has now been confirmed as the main headliner. This show will be his only U.S. performance of this year, and will find him celebrating the 30th anniversary of the band’s album, Abigail, by performing it in full. So if the insane lineup wasn’t enough to get you to order tickets already, the addition of King Diamond surely is! Long live the KING!
