Angie Martinez just threw it back on her Instagram, posting this classic pic of Jay-Z and Michael Jackson backstage at Summer Jam 2001…a monumental performance! Be sure to tune into Hot 97 at 4pm today when Angie and the whole Hot 97 staff announce the lineup for THIS year’s Summer Jam! And of course you want to be in the building at MetLife Stadium on June 3rd (a month from today) to witness it live…especially because you know there will be TONS of unannounced special guests!
