I have an interesting history with ghost live shows.
I was in the middle of a move from houston to denver in spring 2012; the opeth/mastadon/ghost show in denver was 2 months before I moved, and I totally would have gone as I had already seen opeth a few times and was a pretty big fan. That could have been my exposure to them. But alas, I soon after heard of ghost and checked them out at a club in Boulder in 2014, they played 8 of 10 of the first album and 8 of 10 of the second, so I'm glad I got to see that as those two albums are still my favorite, with each subsequent album kinda of straying from what I like about them.
Then the next time they came in '15 it was on the night of my oldest kid's birthday! so I missed that one. Then they came in '16 and '17 and I remember being pissed the price was going up.. it was like $60 or so plus fees (compared to $20 just a few years earlier).. wish I went to 1 or both of them because it wast the last time they'd come to a smaller venue, it was the paramount and fillmore and still had a good chunk of songs of the second album, my favorite.
Then they came to springs and loveland, 2 nights in a row, both larger arenas. I got tix to the second show in the springs, and I straight up forgot to go lol. I remembered the next morning. I still have the unused ticket stub. I was so pissed, in my several hundred concerts I've been to, it was the first time I simply forgot it was happening. Had I bought tickets to the first night, I would have remembered the next day and at least could have gone to the second one.
Seen them twice since then at ball arena and now last month at pavillion. Still like them, but kind of loathe the larger venues. Man I wish I could go back in time and go to those club shows I skipped out on, or if the opeth show was about 6 weeks later.
