Katy Perry gears up for sci-fi inspired world tour | AP interview

Katy Perry says her new sci-fi-inspired world tour is "Disneyland on wheels." The pop star kicks off her tour Wednesday in Mexico City after a whirlwind few months including releasing an album, campaigning for Vice President Kamala Harris and making a brief trip to space. She sat down with AP entertainment journalist Krysta Fauria at her Southern California rehearsal space to talk about the importance of live music, what fans can expect in the show's sets and costumes — and her personal growth through the practice of transcendental meditation. #katyperry
