Yes, the Pepsi Center is home to the Colorado Avalanche and the Denver Nuggets, but the 18,000-seat arena is also the place to see music megastars — from legends who've been touring the globe for decades, like the Who and U2, as well as artists who've moved up in the ranks over the years, like Lady Gaga, who played the Gothic Theatre in 2009; Arcade Fire, whose first stop in Denver was the Larimer Lounge in 2004; and Lorde, who headlined the Fillmore four years ago. If you're looking for a big show with big production, you can't beat the Pepsi Center.
