Aaron Rodgers is gearing up for the new season with some tunes ... checking out his good friend Mike.'s concert in NYC -- and he had the best seat in the house!!
The New York Jets quarterback and his fellow Big Apple star, Yankees pitcher Marcus Stroman, were VIP guests at the musician's sold-out "Upside Down Tour" gig at the Rooftop at Pier 17 on Thursday ... and they appeared to be having a blast.
Rodgers and Mike.
