The potential obstruction with Section 103 at Solider Field for an end-stage concert is the sound and lighting equipment on the side of the stage + some seats are almost behind the stage so you will be looking at a performers' back. Typically, seats behind a performer are usually sold as limited-view tickets.

Lower number seats (1, 2, 3 etc.) in lower rows are less likely to be obstructed and are actually among the best concert seats at Solider Field.
