Great topic, Ben.
What are the reasons why you go see a live show? And..What are the reasons (show related) that prevent you from seeing a favorite band live?
I go see live shows for the energy, and to see the artist who wrote and recorded the songs I love play them live and give me a sense of being a part of the music. It brings the music closer to you, as a fan, if that makes sense. Artists always say once they release a song, it isn't theirs any longer -- they belong to the fans to a certain extent. And I agree with that. We all identify with certain music, for whatever reason, and seeing the people who wrote and recorded it brings a certain connection that is just downright special and addictive.
There are a few reasons why I WOULDN'T go see a favorite band live.
1. Practical -- money, etc. For example, when Helloween was here last, I've wanted to see them since I discovered them in 1988. But leading up to the show, we had a bunch of crazy things happen, and although I had a ticket to the show, I had to drive down (had a rental car), stay the night (had a hotel) and then obviously stuff like food, gas, etc. I just couldn't justify it and ate the ticket to the show, and saved all the money on the travel. It destroyed me. I couldn't listen to Helloween for like a year. And while I made the correct decision not going, it still really bothers me.
2. Personal - sometimes you know a band just isn't able to replicate the music you love. That could be due to age, ability, or both. For example, I saw Tesseract on the Altered State tour in San Francisco. One of the worst shows I've ever been to, even though I love that album to death. They played with one guitarist, since the other one had an emergency and had to fly back to Europe. So instead of hiring a player, the other guitarist just piped in the missing guitarists parts. So that was one fake instrument. The fake keyboards were another (I get it, since they never had a keyboard player). But then the biggest thing -- no one but the lead singer in the band at the time, Ashe O'Hara, could sing. Well, Altered State has TONS of vocal layering. And instead of the other musicians singing along with Ashe, Ashe literally sang to an entire lead vocal backing track, picking spots here and there to actually sing.
People there loved the performance, to me, it was insulting. Complete fakery except for one guitar, the drums, and the bass. I've never seen Tesseract since (I assume they do this with the current singer too).
The age factor is also a thing. There are some bands that I would LIKE to check off the box on, but I won't because they are unable to perform to a level they are accustomed to.
Missing members also bugs me. Bands, particularly live, really have a personality and sound to them that are driven by distinctive players. If you lose too many of those distinctive players, while you can make it sound great in the studio, it's not the same live. So that plays into whether I see an older act tour these days.
That can also be a positive, I mean, Living Colour and Armored Saint ALWAYS deliver, and they sound better now than they did 20 years ago. The dedication to performing and keeping up to the high standards is there. Sadly, not all bands care as much about that.
