So the “secret” Eminem/Jay-Z show on the roof of the Ed Sullivan Theater, initially thought to be a casualty of the dreaded Drake Riot Aftermath, actually happened last night, a mini-performance to air on Late Show with David Letterman Friday to promote both the duo’s upcoming concerts and Em’s new (not very good!) Recovery. (Marshall popped by Bowery Ballroom last night as well.) No riots, no calamity. And the result: NY Post close-up video footage of a fan’s digital-camera footage. Glad everything’s back to normal.
