Editor’s Note: When Katy Perry rolls into town, she does so with one hell of an arsenal. Few modern-day pop stars can fill a 21-song set like she can, and as her latest tour rolled into TD Garden last night (September 29), fans were treated to not only a spotlight on her summer album Witness, but a full-on hit parade coloring her entire career. And Perry’s hits are plentiful; from unofficial Vanyaland anthem “Dark Horse” to familiar faves like “Hot N Cold,” “California Gurls,” “Teenage Dream,” “Roar,” and “Firework,” Perry’s catalog remains impressive. New tracks like “Roulette,” “Swish Swish,” and “Chained to the Rhythm” feel right at home among the crowd favorites, and helped shape her ongoing Witness: The Tour run of North America. In case you missed last night’s gig, fear not — Vanyaland’s Matthew Shelter was under the banners for a full gallery of her early performance, including some chronological shots of her stage unveiling, and Perry is back at the Garden for a second show this evening. Scan through Shelter’s full gallery below, which has now been updated to include a few shots of opener Noah Cyrus.
