What city is this ticket for?
Mystery solved: Just checked the Bellagio reference again (which probably should've been my second resort after the coffee table book). Looks like a private corporate event at the Atlanta Georgia Marriott Marquis Ballroom. Until I thought to also look there I couldn't tell if it was Atlanta, NYC, or DC.
I really like the themed background on this ticket. Much more fitting the band than the average Ticketron fare.
