Section 121 is near the side of the stage but is slightly in front of it. This angle should put you in a good place to see the stage but not in an ideal location. Most likely you will have an unobstructed view of the stage, but depending on the performer, there is a chance that they could put something in front of you that could potentially obstruct your view. To be safe, it would be a good idea to consider Section 123 or 124 which are close by but will have a better angle to see the stage.
