Not just you. There's been a huge pushback in the local music community around this. Concerts listings now prominently feature the name of the poster designer! Humans FTW.
One of the coolest things about seeing a show at the Fillmore is getting the posters they hand out. A number of bands sell, or have their artists, sell show posters (which then become collectible limited editions); it's way less offensive when it's King Gizzard and the Lizard Wizard than when it's Wizards of the Coast.
Going back over a decade (ETA, actually, wow, over two decades), I used to go to shows, not only to see the bands, but also to make sure I got the poster. This one, made by Tim Gough, escaped me: http://www.oldskull.net/wp-content/uploads/2014/04/timgough-...
A friend also called this the “Party Cannon effect”, in reference to black metal festival posters. When lavish detail is available at the push of a button, simplicity stands out far more.
