@adron hey man! If you're coming to Chicago and want to see metal shows, I definitely recommend going to Reggies. They're one of the best clubs to see metal and they got a ton of awesome groups there. Here's the site: https://www.reggieslive.com/
I also recommend checking out the Metro (my favorite venue) and places like Livewire who book more underground bands (https://livewireloungechicago.com/)
Also check out this site (https://thecmf.com/), which lists all the metal shows taking place around the city.
