Katy Perry released her sophomore album, “Teenage Dream,” at the age of 25, but the 2010 effort pristinely captured the chirpy buoyancy of youth through gooey synth-pop. There was a reason that “Teenage Dream” spawned a record-tying five No. 1 singles on the Hot 100 — it was extremely easy for large audiences to relate to Perry’s themes of euphoria, independence and summer fun, especially with such a likable figure presenting these topics in the catchiest of forms.
Perry is still championing optimism with super-producers Max Martin, Lukasz “Dr. Luke” Gottwald and Cirkut as her sonic guides — see her latest chart-topper, “Roar” — but “PRISM” is also a firm and well-executed step toward adulthood.
