For concerts, the special club amenities afforded during football games are not offered. One perk you will continue to receive is larger, padded seating with additional legroom.
Fans seated in Section 111C-115C for most concerts (including Paul McCartney) at MetLife Stadium will have access to the Coaches Club. The club area may not provide the same benefits as during a Jets or Giants game, but there will be food and drink available for purchase.
The Bruce Springsteen show at MetLife Stadium has one of the more unique field setups for a football-stadium concert. Often times the field is all reserved seating or mostly reserved with a small general admission pit area. For the Springsteen show, the entire field is a general admission area.
There are no seats in any of the general admission areas at MetLife Stadium. Thus, the entire field will be standing, and fans will occupy spaces on a first-come, first-serve basis. Unfortunately, this means you'll have to arrive early to occupy a space close to the stage and that you'll have to stand for the duration of the concert.
