What Capital Cities Learned From Touring With Katy Perry & Her Puppy

Already festival staples, Capital Cities forwent the fest grind this summer and supported Katy Perry on her Prismatic world tour. Returning to the circuit for Austin City Limits 2014, the "Safe and Sound" duo tell us what they learned during the stadium-sized pop extravaganza. 

"It was wonderful because we got the chance to play in front of so many people," says member Sebu Simonian. "We had really not done too many arenas before. Just that big production was a different thing for us. It was a fun experience and a challenge to take on and make into a good thing."
