U2 at Las Vegas’ Sphere on Jan. 26-27 started at $737 before fees on Vivid Seats.Now, just six days later, our team found seats going for as low as $420 before fees.While still rather expensive, that’s a whopping $317 (!) in savings just for practicing patience.Given the show’s impressive bona fides; that’s a steal.“The term immersive doesn’t give this production its due justice,” the New York Post wrote in a glowing review of the show.
