GhostofCain
Ancient Mariner
I have mixed feelings on Ghost. When they opened for Maiden in 2016 I think they did an enjoyable set, and their style seemed like a good fit. Afterwards I tried listening to one of their albums, and was bored out of my mind by the third song... I guess they're a band meant to be experienced in a live setting
As to whether they are (or are destined to become) one of the best rock/metal bands in modern times, well, they are definitely not my top pick.
I would have preferred Ghost opening for Maiden rather than Killswitch Engage or Shinedown on the last two UK tours.
