Husband and Wife both posting on a forum doesn't seem right, like kissing cousins, or the guy that has to bring his wife/GF out on "boys night out".....maybe I need some medication. Maybe hats off to Joe, a guitar player that has a woman fan on his forum, hopefully not to keeping tabs on her other half. :-) nobody get upset :-)
I understand when an artist puts out an album or two that are a departure from what lured you/fan in initially, look at Mayer, which I believe was referenced in this thread, he drops a bomb on his fans with an Americana album. So, when I was buying tix to his 2014 tour, I knew he would support/promote his latest albums/style and that some of my fav tunes wouldn't be played. If I didn't think this would happen, perhaps I need some medication.?. Anyway, I was ok with Mayer show, I think the fan/me benefited more, as I got to see artist excited to play his new/fresh tunes and to expand on them live to take them to new places. Artist and Fan Win.
If you want only what you deem as an artist best work or era of work, there's always DVD's to buy....stay home, or, go to Vegas, where there is plenty of duplicated greatest hits performed night after night.
If artist continues year after year, or album after album down another a path you don't like, you stop supporting artist live...like not going back to a restaurant that only serves food you don't like....you will replaced by another patron, a new patron.
