for a concert at joe louis arena is sectio 226 A good seats

You are 2nd level which is the upper bowl on/in the back/far right corner from the stage. Basically depending what row, you a fair distance away fro the stage. Good sight lines however all throughout. here is a link to seating at Joe Louis:

Honestly, for as old as the venue is, there are not really that many bad seats in the JLA. I've gone to a lot of concerts in the upper level there and had no problem seeing anything. If you click on that link that Defenders of the Cup has, and click on the map, it will turn into an interactive map and if you click on your section, you can have a bird is eye view of where you will be sitting. If you have an end-stage setup, you will be just fine.

Have fun!
