Review Summary: Not her most mature work.
Opening track "Roar" is her bold clitché-club of "Prism" with tacky part from Survivor's iconic hit, "Eye of the Tiger". Anthem from Disney's sweet cartoon sounds kinda boring and predictable with "Brave"-ish beatline.
Is "Birthday" outtake from "Teenage Dream"? I doubt that Maraih Carey would begin to put down an empty vulgar track for the classic debut album. Most likely, this song will be the anthem of advertizing of children's holidays because of the commercial bubble-gum nature. "California Gurls" reminiscence in high form without any changes. Club-popping soundtracks, "This Is How We Do" and "Dark Horse" are interesting things, of course, but don't deserve to give them a winner's place.
Perry's favorite song from album, "Unconditionally" sounds very gorgeous with pure vocal and continuous percussions. Perhaps, "Unconditionally" can easily becomes the song with the deepest and clear value. Perry doesn't try to hide the identity behind infinite luscious metaphors.
The most part of an "Prism" can seem imperceptible as the main attention will be paid to senseless songs from the first half of record. "This Moment" smells like Perry's most growing-up track of this record. But I can't deny only sad fact about song: the production excessively callous and mechanical. "Double Rainbow" was written with Sia, but this it's not reminds about her old smash hits as "Diamonds" or "Titanium". Shoegazing track with ambient elements easily became the deepest and impressionable reminiscence from "Prism".
Overall, "Prism" doesn't sound harmoniously and consistently: the most part of songs wants to be forgotten, as unsuccessful comedy experiment. Perry slowly and uncertainly rises as songwriter, but she's blindly looking for unexplored sides of herself. "Do you ever think that we're just chasing our tails?".
